What is CVE-2026-45578?
CVE-2026-45578 is a high-severity command injection vulnerability in Wwbn Avideo, published on 29 May 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
WWBN AVideo is an open source video platform. In 29.0 and earlier, there is a classic shell-metacharacter injection. The YPTSocket notification branch in plugin/Live/on_publish.php builds an execAsync() command line by string concatenation, single-quoting each argument but never calling escapeshellarg(). A ' in any of the three interpolated values ($users_id, $m3u8, $obj->liveTransmitionHistory_id) closes the quoted token and lets the attacker append arbitrary commands.
Weakness: CWE-78
