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.
Analysis
SQL injection in WWBN AVideo versions up to 26.0 allows unauthenticated remote attackers to extract sensitive database contents and modify data through the RTMP publish authentication stream key validation mechanism. The vulnerability (CVSS 9.1 Critical) arises from unsanitized string interpolation in Live_schedule::keyExists() fallback logic, affecting the open-source video platform's live streaming infrastructure. …

Remediation
Within 24 hours: Inventory all WWBN AVideo instances and document versions in use; immediately disable RTMP live streaming if not operationally critical. Within 7 days: Implement network-level access controls to restrict RTMP publish endpoints to trusted sources only; review database access logs for indicators of SQL injection attempts. …
