# CVE-2026-43881: WWBN AVideo: Unauthenticated User Enumeration in \`objects/users.json.php\` via \`isCompany\` Parameter Flips \`$ignoreAdmin = true\` and Defeats Admin-Only Listing Guard

- Also known as: GHSA-6RVW-7P8V-MJFQ
- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
- CISA SSVC: exploitation=poc, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-05-11 · Updated: 2026-05-12

## Affected

- WWBN AVideo: through 29.0
- wwbn/avideo (Packagist): through 29.0

## Description

WWBN AVideo is an open source video platform. In versions up to and including 29.0, objects/users.json.php exposes two unauthenticated paths that disclose the full set of registered user accounts. The isCompany request parameter causes the handler to set $ignoreAdmin = true for any non-admin caller (including unauthenticated visitors), which defeats the admin-only guard inside User::getAllUsers()/User::getTotalUsers(). A second path accepts users_id and calls User::getUserFromID() directly with no permission check, producing a single-user oracle. Both paths return id, identification (display name), channel URL, photo, background, and status, plus the total account count. Commit d9cdc702481a626b15f814f6093f1e2a9c20d375 contains an updated fix.
