CVE-2026-33723Public exploitNetwork attack vector

Authenticated database disclosure via concatenated user identifier

Published Mar 23, 2026 · Updated Mar 23, 2026

SQL injection in AVideo 26.0 and earlier allows remote authenticated users to read database data through a crafted user_id value. Subscribe::save() inserts the unsanitized property derived from POST user_id into an INSERT statement instead of binding it as a parameter. Any authenticated account can target a previously unsubscribed user identifier to extract arbitrary table data or insert rows into the subscribes table.
