CVE-2026-33867: AVideo has Plaintext Video Password Storage
WWBN AVideo is an open source video platform.
CVSS 9.1 Critical EPSS 0.2% · p5
Should you act?
Critical and remotely reachable
No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Not in CISA KEV, but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.2%, percentile 5: FIRST’s model estimates a 0.2% chance of exploitation activity in the next 30 days, higher than 5% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes
wwbn/avideo(Composer (PHP)) <= 26.0, no fixed version listed. Check your lockfile, including transitive dependencies.
What it is
WWBN AVideo is an open source video platform. In versions up to and including 26.0, AVideo allows content owners to password-protect individual videos. The video password is stored in the database in plaintext — no hashing, salting, or encryption is applied. If an attacker gains read access to the database (via SQL injection, a database backup, or misconfigured access controls), they obtain all video passwords in cleartext. Commit f2d68d2adbf73588ea61be2b781d93120a819e36 contains a patch.
