CVE-2026-64625: Wwbn Avideo

Critical severity, CVSS 9.8. EPSS: 0.6% chance of exploitation in the next 30 days.

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.
