What happened

Topluyo Desktop for Linux prior to 2026.9.2410 unsafely processes user-controlled URLs in the openExternalLinks() routine in utils.js, enabling OS command injection.

Why it is dangerous: An attacker who controls a link the user opens can execute arbitrary operating system commands with the privileges of the logged-in user, potentially taking over that account's files and data.
