## The brief

Ubuntu has patched a Kdenlive project-file issue affecting 26.04 LTS. The advisory says dangerous proxy parameters could pass through to MLT consumer properties and allow attacker-controlled projects to execute commands. It lists updates for Kdenlive and the MLT packages, tying the risk to opening a malicious project rather than ordinary video playback.
