• CVE-2026-40907: 0.27% estimated exploitation activity in the next 30 days; percentile 19.10 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary The endpoint plugin/Live/view/Liverestreams/list.json.php contains an Insecure Direct Object Reference (IDOR) vulnerability that allows any authenticated user with streaming permission to retrieve other users' live restream configurations, including third-party platform stream keys and OAuth tokens (accesstoken, refreshtoken) for services like YouTube Live, Facebook Live, and Twitch. Details The authorization logic in list.json.php is intended to restrict non-admin users to viewing only their own restream records. However, the implementation at lines 10-14 only enforces this when the usersid GET parameter is absent: When a non-admin user explicitly supplies ?usersid=<victimid, the value is non-empty, so the override at line 12 is never reached. The attacker-controlled ID passes directly to getAllFromUser(), which executes: This returns all columns from the liverestreams table, including: - streamkey (VARCHAR 500) — the victim's RTMP stream key for third-party platforms -…

# Patch Next advisory brief: CVE-2026-40907

Advisory: WWBN AVideo has an IDOR in Live Restreams list.json.php Exposes Other Users' Stream Keys and OAuth Tokens
IDs: CVE-2026-40907, GHSA-gpgp-w4x2-h3h7
Record: https://patchnext.com/advisories/cve-2026-40907 (revision 1, source checked 26 Oct 2026, 14:39 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist wwbn/avideo: affected <= 29.0

## Suggested inspection (read-only)
- Packagist wwbn/avideo: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on wwbn/avideo.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-gpgp-w4x2-h3h7 (GitHub-reviewed advisory GHSA-gpgp-w4x2-h3h7 lists affected ranges: Packagist wwbn/avideo >=0 <=29.0)
