+## 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

+final release until late august unless something bad happens and i end up building this thing on a shinkansen
+
+## recent security / vulnerability fixes

+* [v1.8.7](https://github.com/9001/copyparty/releases/tag/v1.8.7) (2023-07-23) - [CVE-2023-38501](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-38501) - reflected XSS
+* [v1.8.2](https://github.com/9001/copyparty/releases/tag/v1.8.2) (2023-07-14) - [CVE-2023-37474](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-37474) - path traversal (first CVE)
+  * all serverlogs reviewed so far (5 public servers) showed no signs of exploitation
+
+## bugfixes
+* range-select with shiftclick:
+  * don't crash when entering another folder and shift-clicking some more
+  * remember selection origin when lazy-loading more stuff into the viewport
+* markdown editor:
+  * fix confusing warnings when the browser cache decides it *really* wants to cache
+  * and when a document starts with a newline
+* remember intended actions such as `?edit` on login prompts
+* Windows: TLS-cert generation (triggered by network changes) could occasionally fail

+# 2023-0723-1543  `v1.8.7`  XSS for days
+
+at the lack of better ideas, there is now a [discord server](https://discord.gg/25J8CdTT6G) with an `@everyone` for all future important updates such as this one
+
+## bugfixes
+* reflected XSS through `/?k304` and `/?setck`
+  * if someone tricked you into clicking a URL containing a chain of `%0d` and `%0a` they could potentially have moved/deleted existing files on the server, or uploaded new files, using your account
+  * if you use a reverse proxy, you can check if you have been exploited like so:
+    * nginx: grep your logs for URLs containing `%0d%0a%0d%0a`, for example using the following command:
+      ```bash
+      (gzip -dc access.log*.gz; cat access.log) | sed -r 's/" [0-9]+ .*//' | grep -iE '%0[da]%0[da]%0[da]%0[da]'
+      ```
+  * if you find any traces of exploitation (or just want to be on the safe side) it's recommended to change the passwords of your copyparty accounts
+  * huge thanks *again* to @TheHackyDog !
+* the original fix for CVE-2023-37474 broke the download links for u2c.py and partyfuse.py
+* fix mediaplayer spinlock if the server only has a single audio file
+

+# 2023-0721-0036  `v1.8.6`  fix reflected XSS
+
+## bugfixes
+* reflected XSS through `/?hc` (the optional subfolder parameter to the [connect](https://a.ocv.me/?hc) page)
+  * if someone tricked you into clicking `http://127.0.0.1:3923/?hc=<script>alert(1)</script>` they could potentially have moved/deleted existing files on the server, or uploaded new files, using your account
+  * if you use a reverse proxy, you can check if you have been exploited like so:
+    * nginx: grep your logs for URLs containing `?hc=` with `<` somewhere in its value, for example using the following command:
+      ```bash
+      (gzip -dc access.log*.gz; cat access.log) | sed -r 's/" [0-9]+ .*//' | grep -E '[?&](hc|pw)=.*[<>]'
+      ```
+  * if you find any traces of exploitation (or just want to be on the safe side) it's recommended to change the passwords of your copyparty accounts

+# 2023-0718-0746  `v1.8.4`  range-select v2
+
+**IMPORTANT:** `v1.8.2` (previous release) fixed [CVE-2023-37474](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-37474) ; please see the [1.8.2 release notes](https://github.com/9001/copyparty/releases/tag/v1.8.2) (all serverlogs reviewed so far showed no signs of exploitation)
+
+* 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/)
+
+## 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`
+

ed	007d948cb9	fix GHSA-f54q-j679-p9hh: reflected-XSS in cookie-setters; it was possible to set cookie values which contained newlines, thus terminating the http header and bleeding into the body. We now disallow control-characters in queries, but still allow them in paths, as copyparty supports filenames containing newlines and other mojibake. The changes in `set_k304` are not necessary in fixing the vulnerability, but makes the behavior more correct.	2023-07-23 10:55:08 +00:00
