Summary
mpv, a media player, has a playlist injection flaw in its bundled ytdl_hook script that lets an attacker, remotely and without logging in, add unchecked entries by embedding newlines in playlist URLs in a feed or page that a user opens. By bypassing the URL safety check, the attacker can open file:// or av:// inputs to read local files or load shared objects via ladspa, which can lead to code execution.
Read the original description
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.

Questions about CVE-2026-123095
Is CVE-2026-123095 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
A playlist entry URL containing a line break is split into several entries by the bundled ytdl_hook script. The split lets an entry bypass the url_is_safe() check and open file:// or av:// inputs, which can allow reading local files or loading shared objects via ladspa for code execution.Source: vulncheck.com, github.com
Which versions are affected by CVE-2026-123095?
mpv: from 0.29.0 before 0.42.0.Source: cve.now feed data
Am I affected, and how do I check?
mpv versions from 0.29.0 up to but not including 0.42.0 are affected when the bundled ytdl_hook script is involved. To check a version, run mpv --version and compare the number with 0.42.0.Source: vulncheck.com, github.com
How do I fix CVE-2026-123095?
Upgrade mpv to 0.42.0 or later, which contains the fix.Source: vulncheck.com, github.com
