+# 2023-0831-2211  `v1.9.3`  iOS and http fixes
+
+## new features
+* iPhones and iPads are now able to...
+  * 9986136dfb2364edb35aa9fbb87410641c6d6af3 play entire albums while the screen is off without the music randomly stopping
+    * apple keeps breaking AudioContext in new and interesting ways; time to give up (no more equalizer)
+  * 1c0d978979a703edeb792e552b18d3b7695b2d90 perform search queries and execude js code
+    * by translating [smart-quotes](https://stackoverflow.com/questions/48678359/ios-11-safari-html-disable-smart-punctuation) into regular `'` and `"` characters
+* python 3.12 support
+  * technically a bugfix since it was added [a year ago](https://github.com/9001/copyparty/commit/32e22dfe84d5e0b13914b4d0e15c1b8c9725a76d) way before the first py3.12 alpha was released but turns out i botched it, oh well
+* filter error messages so they never include the filesystem path where copyparty's python files reside
+* print more context in server logs if someone hits an unexpected permission-denied
+
+# bugfixes
+found some iffy stuff combing over the code but, as far as I can tell, luckily none of these were dangerous:
+* URL normalization was a bit funky, but it appears everything access-control-related was unaffected
+* some url parameters were double-decoded, causing the unpost filtering and file renaming to fail if the values contained `%`
+* clients could cause the server to return an invalid cache-control header, but newlines and control-characters got rejected correctly
+* minor cosmetics / qol fixes:
+  * reduced flickering on page load in chrome
+  * fixed some console spam in search results
+  * markdown documents now have the same line-height in directory listings and the editor
+

+# 2023-0826-2116  `v1.9.2`  bigger hammer
+
+## new features
+* more ways to automatically ban users! three new sensors, all default-enabled, giving a 1 day ban after 9 hits in 2 minutes:
+  * `--ban-403`: trying to access volumes that dont exist or require authentication
+  * `--ban-422`: invalid POST messages (from brutefocing POST parameters and such)
+  * `--ban-url`: URLs which 404 and also match `--sus-urls` (scanners/crawlers)
+  * if you want to run a vulnerability scan on copyparty, please just [download the server](https://github.com/9001/copyparty/releases/latest/download/copyparty-sfx.py) and do it locally! takes less than 30 seconds to set up, you get lower latency, and you won't be filling up the logfiles on the demo server with junk, thank you 🙏
+* more ban-related stuff,
+  * new global option `--nonsus-urls` specifies regex of URLs which are OK to 404 and shouldn't ban people
+  * `--turbo` now accepts the value `-1` which makes it impossible for clients to enable it, making `--ban-404` safe to use
+* range-selecting files in the list-view by shift-pgup/pgdn
+* volumes which are currently unavailable (dead nfs share, external HDD which is off, ...) are marked with a ❌ in the directory tree sidebar
+* the toggle-button to see dotfiles is now persisted as a cookie so it also applies on the initial page load
+* more effort is made to prevent `<script>`s inside markdown documents from running in the markdown editor and the fullpage viewer
+  * anyone who wanted to use markdown files for malicious stuff can still just upload an html file instead, so this doesn't make anything more secure, just less confusing
+  * the safest approach is still the `nohtml` volflag which disables markdown rendering outside sandboxes entirely, or only giving out write-access to trustworthy people
+  * enabling markdown plugins with `-emp` now has the side-effect of cancelling this band-aid too
+
+## bugfixes
+* textfile navigation hotkeys broke in the previous version
+
+## other changes
+* example [nginx config](https://github.com/9001/copyparty/blob/hovudstraum/contrib/nginx/copyparty.conf) was not compatible with cloudflare (suggest `$http_cf_connecting_ip` instead of `$proxy_add_x_forwarded_for`)
+* `copyparty.exe` is now built with python 3.11.5 which fixes [CVE-2023-40217](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-40217)
+  * `copyparty32.exe` is not, because python understandably ended win7 support 
+* [similar software](https://github.com/9001/copyparty/blob/hovudstraum/docs/versus.md):
+  * copyparty appears to be 30x faster than nextcloud and seafile at receiving uploads of many small files
+  * seafile has a size limit when zip-downloading folders

+# 2023-0820-2338  `v1.9.1`  prometheable
+
+## new features
+* #49 prometheus / grafana / openmetrics integration ([see readme](https://github.com/9001/copyparty#prometheus))
+  * read metrics from http://127.0.0.1:3923/.cpr/metrics after enabling with `--stats`
+* download a folder with all music transcoded to opus by adding `?tar=opus` or `?zip&opus` to the URL
+  * can also be used to download thumbnails instead of full images; `?tar=w` for webp, `?tar=j` for jpg
+    * so i guess the long-time requested feature of pre-generating thumbnails kind of happened after all, if you schedule a `curl http://127.0.0.1:3923/?tar=w >/dev/null` after server startup
+* u2c (commandline uploader): argument `-x` to exclude files by regex (compares absolute filesystem paths)
+* `--zm-spam 30` can be used to improve zeroconf / mDNS reliability on crazy networks
+  * only necessary if there are clients with multiple IPs and some of the IPs are outside the subnets that copyparty are in -- not spec-compliant, not really recommended, but shouldn't cause any issues either
+  * and `--mc-hop` wasn't actually implemented until now
+* dragging an image from another browser window onto the upload button is now possible
+  * only works on chrome, and only on windows or linux (not macos)
+* server hostname is prefixed in all window titles
+  * can be adjusted with `--bname` (the file explorer) and `--doctitle` (all other documents)
+  * can be disabled with `--nth` (just window title) or `--nih` (title + header)
+
+## bugfixes
+* docker: the autogenerated seeds for filekeys and account passwords now get persisted to the config volume (thx noktuas)
+* uploading files with fancy filenames could fail if the copyparty server is running on android
+* improve workarounds for some apple/iphone/ios jank (thx noktuas and spiky)
+  * some ui elements had their font-size selected by fair dice roll
+  * the volume control does nothing because [apple disabled it](https://developer.apple.com/library/archive/documentation/AudioVideo/Conceptual/Using_HTML5_Audio_Video/Device-SpecificConsiderations/Device-SpecificConsiderations.html#//apple_ref/doc/uid/TP40009523-CH5-SW11), so add a warning
+  * the image gallery cannot be fullscreened [as apple intended](https://developer.mozilla.org/en-US/docs/Web/API/Element/requestFullscreen#browser_compatibility) so add a warning
+
+## other changes
+* file table columns are now limited to browser window width
+* readme: mention that nginx-QUIC is currently very slow (thx noktuas)
+* #50 add a safeguard to the wget plugin in case wget at some point adds support for `file://` or similar
+* show a suggestion on startup to enable the database

+## new features
+* #47 file selection by shift-clicking
+  * in list-view: click a table row to select it, then shift-click another to select all files in-between
+  * in grid-view: either enable the `multiselect` button (mainly for phones/tablets), or the new `sel` button in the `[⚙️] settings` tab (better for mouse+keyboard), then shift-click two files
+* volflag `fat32` avoids a bug in android's sdcardfs causing excessive reindexing on startup if any files were modified on the sdcard since last reboot
+
+## bugfixes
+* minor corrections to the new features from #45
+  * uploader IPs are now visible for `a`dmin accounts in `d2t` volumes as well
+
+## other changes
+* the admin-panel is only accessible for accounts which have the `a` (admin) permission-level in one or more volumes; so instead of giving your user `rwmd` access, you'll want `rwmda` instead:
+  ```bash
+  python3 copyparty-sfx.py -a joe:hunter2 -v /mnt/nas/pub:pub:rwmda,joe
+  ```
+  or in a settings file,
+  ```yaml
+  [/pub]
+    /mnt/nas/pub
+    accs:
+      rwmda: joe
+  ```
+  * until now, `rw` was enough, however most readwrite users don't need access to those features
+  * grabbing a stacktrace with `?stack` is permitted for both `rw` and `a`

+
+* read-only demo server at https://a.ocv.me/pub/demo/
+* [docker image](https://github.com/9001/copyparty/tree/hovudstraum/scripts/docker) ╱ [similar software](https://github.com/9001/copyparty/blob/hovudstraum/docs/versus.md) ╱ [client testbed](https://cd.ocv.me/b/)
+
+Starting with the bad and important news; this release fixes https://github.com/9001/copyparty/security/advisories/GHSA-pxfv-7rr3-2qjg / [CVE-2023-37474](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-37474) -- so please upgrade!
+
+Every version until now had a [path traversal vulnerability](https://owasp.org/www-community/attacks/Path_Traversal) which allowed read-access to any file on the server's filesystem. To summarize,
+* Every file that the copyparty process had the OS-level permissions to read, could be retrieved over HTTP without password authentication
+* However, an attacker would need to know the full (or copyparty-module-relative) path to the file; it was luckily impossible to list directory contents to discover files on the server
+* You may have been running copyparty with some mitigations against this:
+  * [prisonparty](https://github.com/9001/copyparty/tree/hovudstraum/bin#prisonpartysh) limited the scope of access to files which were intentionally given to copyparty for sharing; meaning all volumes, as well as the following read-only filesystem locations: `/bin`, `/lib`, `/lib32`, `/lib64`, `/sbin`, `/usr`, `/etc/alternatives`
+  * the [nix package](https://github.com/9001/copyparty#nix-package) has a similar mitigation implemented using systemd concepts
+  * [docker containers](https://github.com/9001/copyparty/tree/hovudstraum/scripts/docker) would only expose the files which were intentionally mounted into the container, so even better
+* More conventional setups, such as just running the sfx (python or exe editions), would unfortunately expose all files readable by the current user
+* The following configurations would have made the impact much worse:
+  * running copyparty as root
+
+So, three years, and finally a CVE -- which has been there since day one... Not great huh. There is a list of all the copyparty alternatives that I know of in the `similar software` link above.
+
+Thanks for flying copyparty! And especially if you decide to continue doing so :-)
+
+## new features
+* #43 volflags to specify thumbnailer behavior per-volume;
+  * `--th-no-crop` / volflag `nocrop` to specify whether autocrop should be disabled
+  * `--th-size` / volflag `thsize` to set a custom thumbnail resolution
+  * `--th-convt` / volflag `convt` to specify conversion timeout
+* #45 resulted in a handful of opportunities to tighten security in intentionally-dangerous setups (public folders with anonymous uploads enabled):
+  * a new permission, `a` (in addition to the existing `rwmdgG`), to show the uploader-IP and upload-time for each file in the file listing
+    * accidentally incompatible with the `d2t` volflag (will be fixed in the next ver)
+  * volflag `nohtml` is a good defense against (un)intentional XSS; it returns HTML-files and markdown-files as plaintext instead of rendering them, meaning any malicious `<script>` won't run -- bad idea for regular use since it breaks fundamental functionality, but good when you really need it
+    * the README-previews below the file-listing still renders as usual, as this is fine thanks to the sandbox
+  * a new eventhook `--xban` to run a plugin when copyparty decides to ban someone (for password bruteforcing or excessive 404's), for example to blackhole the IP using fail2ban or similar
+
+## bugfixes
+* **fixes a path traversal vulnerability,** https://github.com/9001/copyparty/security/advisories/GHSA-pxfv-7rr3-2qjg / [CVE-2023-37474](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-37474)
+  * HUGE thanks to @TheHackyDog for reporting this !!
+  * if you use a reverse proxy, you can check if you have been exploited like so:
+    * nginx: grep your logs for URLs containing both `.cpr/` and `%2[^0]`, for example using the following command:
+      ```bash
+      (gzip -dc access.log.*.gz; cat access.log) | sed -r 's/" [0-9]+ .*//' | grep -E 'cpr/.*%2[^0]' | grep -vF data:image/svg
+      ```
+* 77f1e5144455eb946db7368792ea11c934f0f6da fixes an extremely unlikely race-condition (see the commit for details)
+* 8f59afb1593a75b8ce8c91ceee304097a07aea6e fixes another race-condition which is a bit worse:
+  * the unpost feature could collide with other database activity, with the worst-case outcome being aborted batch operations, for example a directory move or a batch-rename which stops halfways

+
+News: if you use rclone as a copyparty webdav client, upgrading to [rclone v1.63](https://github.com/rclone/rclone/releases/tag/v1.63.0) (just released) will give you [a huge speed boost](https://github.com/rclone/rclone/pull/6897) for small files
+
+## new features
+* #39 hashed passwords
+  * instead of keeping plaintext account passwords in config files, you can now store hashed ones instead
+  * `--ah-alg` specifies algorithm; best to worst: `argon2`, `scrypt`, `sha2`, or the default `none`
+  * the default settings of each algorithm takes `0.4 sec` to hash a password, and argon2 eats `256 MiB` RAM
+    * can be adjusted with optional comma-separated args after the algorithm name; see `--help-pwhash`
+  * `--ah-salt` is the [static salt](https://github.com/9001/copyparty/blob/hovudstraum/docs/devnotes.md#hashed-passwords) for all passwords, and is autogenerated-and-persisted if not specified
+  * `--ah-cli` switches copyparty into a shell where you can hash passwords interactively
+    * but copyparty will also autoconvert any unhashed passwords on startup and give you the values to insert into the config anyways
+* #40 volume size limit
+  * volflag `vmaxb` specifies max size of a volume
+  * volflag `vmaxn` specifies max number of files in a volume
+  * example: `-v [...]:c,vmaxb=900g:c,vmaxn=20k` blocks uploads if the volume reaches 900 GiB or a total of 20480 files
+  * good alternative to `--df` since it works per-volume
+
+## bugfixes
+* autogenerated TLS certs didn't include the mDNS name
+
+## other changes
+* improved cloudflare challenge detection
+* markdown edits will now trigger upload hooks

+* auto-generate TLS certificates on startup / network-change
+  * mostly good for LAN, requires [cfssl](https://github.com/cloudflare/cfssl/releases/latest), can be disabled with `--no-crt`

+    * so it's still recommended to use a reverse-proxy / letsencrypt for WAN servers
+* the default `--fk-salt` is now much stronger
+  * all existing installations will keep the previously selected seed -- you can choose to upgrade by deleting `~/.config/copyparty/cert.pem` but this will change all filekeys / per-file passwords
+* the `NO_COLOR` environment-variable is now supported, removing colors from stdout
+  * see https://no-color.org/ and more importantly https://youtu.be/biW5UVGkPMA?t=150

 I didn't know about [tus](https://tus.io/)  when I made this, but:
 * up2k has the advantage that it supports parallel uploading of non-contiguous chunks straight into the final file -- [tus does a merge at the end](https://tus.io/protocols/resumable-upload.html#concatenation) which is slow and taxing on the server HDD / filesystem (unless i'm misunderstanding)
 * up2k has the slight disadvantage of requiring the client to hash the entire file before an upload can begin, but this has the benefit of immediately skipping duplicate files
  * and the hashing happens in a separate thread anyways so it's usually not a bottleneck

+# hashed passwords
+
+regarding the curious decisions
+
+there is a static salt for all passwords;
+* because most copyparty APIs allow users to authenticate using only their password, making the username unknown, so impossible to do per-account salts
+* the drawback of this is that an attacker can bruteforce all accounts in parallel, however most copyparty instances only have a handful of accounts in the first place, and it can be compensated by increasing the hashing cost anyways

ed	c1efd227b7	fix inconsistent use of symlink mtimes in database; on upload, dupes are by default handled by symlinking to the existing copy on disk, writing the uploader's local mtime into the symlink mtime, which is also what gets indexed in the db this worked as intended, however during an -e2dsa rescan on startup the symlink destination timestamps would be used instead, causing a reindex and the resulting loss of uploader metadata (ip, timestamp) will now always use the symlink's mtime; worst-case 1% slower startup (no dhash) this change will cause a reindex of incorrectly indexed files, however as this has already happened at least once due to the bug being fixed, there will be no additional loss of metadata	2023-09-01 20:29:55 +00:00

ed	b8adeb824a	misc http correctness; some of this looks shady af but appears to have been harmless (decent amount of testing came out ok) * some location normalization happened before unquoting; however vfs handled this correctly so the outcome was just confusing messages * some url parameters were double-decoded (unpost filter, move destinations), causing some operations to fail unexpectedly * invalid cache-control headers could be generated, but not in a maliciously-beneficial way (there are safeguards stripping newlines and control-characters) also adds an exception-message cleanup step to strip away the filesystem path that copyparty's python files are located at, in case that could be interesting knowledge	2023-08-31 21:51:58 +00:00

ed	5d13ebb4ac	avoid firefox-android quirk(?): when repeatedly tapping the next-folder button, occasionally it will reload the entire page instead of ajax'ing the directory contents. Navigation happens by simulating a click in the directory sidebar, so the incorrect behavior matches what would happen if the link to the folder didn't have its onclick-handler attached, so should probably double-check if there's some way for that to happen Issue observed fairly easily in firefox on android, regardless if copyparty is running locally or on a server in a different country. Unable to reproduce with android-chrome or desktop-firefox Could also be due to an addon (dark-reader, noscript, ublock-origin) anyways, avoiding this by doing the navigation more explicitly	2023-08-16 19:56:47 +00:00
