What is CVE-2026-34374?
CVE-2026-34374 is a critical SQL injection vulnerability in Wwbn Avideo, published on 27 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `Live_schedule::keyExists()` method constructs a SQL query by interpolating a stream key directly into the query string without parameterization. This method is called as a fallback from `LiveTransmition::keyExists()` when the initial parameterized lookup returns no results. Although the calling function correctly uses parameterized queries for its own lookup, the fallback path to `Live_schedule::keyExists()` undoes this protection entirely. This vulnerability is distinct from GHSA-pvw4-p2jm-chjm, which covers SQL injection via the `live_schedule_id` parameter in the reminder function. This finding targets the stream key lookup path used during RTMP publish authentication. As of time of publication, no patched versions are available.
Weakness: CWE-89
