CVE-2026-64625 Details
Description
AVideo before 29.0 contains an incomplete fix for CVE-2026-45578 where execAsync() re-wraps escaped commands in double-quoted sh -c, allowing command substitution via $() and backticks. Attackers can inject arbitrary OS commands through the Live plugin on_publish.php endpoint despite escapeshellarg() protection.
A command injection vulnerability has been identified in AVideo versions prior to 29.0. The issue arises from an incomplete fix for a previous vulnerability, CVE-2026-45578. The problem occurs because the execAsync() function re-wraps escaped commands in double-quoted 'sh -c', which allows command substitution through '$()' and backticks. As a result, attackers can inject arbitrary operating system commands via the Live plugin's on_publish.php endpoint, bypassing the intended protection of escapeshellarg().
Users are advised to update AVideo to version 29.0 or later, where this vulnerability has been patched.
