# mpv: playlist URL newlines let attackers open local files or run code

The bundled ytdl_hook script in mpv, a media player, accepts playlist URLs containing embedded newlines and bypasses its url_is_safe() check. An attacker who controls a feed or web page can make mpv open file:// or av:// inputs, which can read local files or load shared objects through ladspa for code execution.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Run `mpv --version` and compare against the fixed release in the product ranges.
- Check whether the bundled ytdl_hook script is in use (mpv's youtube-dl/yt-dlp hook loaded by default).

## Fix

- mpv: `0.42.0`

## From the sources

mpv 0.29.0 before 0.42.0 contains a playlist injection vulnerability in the bundled ytdl_hook script that allows remote attackers to add unchecked entries by embedding newlines in playlist URLs. Attackers controlling a feed or page can bypass url_is_safe() to open file:// or av:// inputs, reading local files or loading shared objects via ladspa for code execution.
