beets: Beets is the media library management system
CVE-2026-42052 is fixed in beets on 1 platform, first by beets 1.4.6-2ubuntu0.1~esm1, released May 4, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Beets is the media library management system. Prior to version 2.10.0, the bundled web UI uses Underscore template interpolation mode <%= ... %> for untrusted metadata fields. In this runtime, <%= ... %> is raw insertion and HTML escaping is only performed by <%- ... %>. Rendered output is then inserted with .html(...), allowing attacker-controlled markup to become active DOM. This issue has been patched in version 2.10.0.
