• CVE-2026-33502: 0.45% estimated exploitation activity in the next 30 days; percentile 39.17 (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 An unauthenticated server-side request forgery vulnerability in plugin/Live/test.php allows any remote user to make the AVideo server send HTTP requests to arbitrary URLs. This can be used to probe localhost/internal services and, when reachable, access internal HTTP resources or cloud metadata endpoints. Details The endpoint accepts $REQUEST['statsURL'] and only checks that it starts with http: It then calls: Inside the same file, urlgetcontents() performs a real outbound request with filegetcontents() when allowurlfopen is enabled: There is: - no authentication check - no allowlist of trusted stats URLs - no SSRF-safe URL validation - reflected response/error output Validated on source: - test.php PoC Target used during validation: 1. Probe a closed localhost port: Observed response excerpt: 2. Probe the local web service itself: This returns upstream connection details from the server-side request and confirms the endpoint can target local/internal HTTP services. Impact…

# Patch Next advisory brief: CVE-2026-33502

Advisory: AVideo has Unauthenticated SSRF via plugin/Live/test.php
IDs: CVE-2026-33502, GHSA-3fpm-8rjr-v5mc
Record: https://patchnext.com/advisories/cve-2026-33502 (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: Critical (CVSS 9.3)
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 <= 26.0

## 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-3fpm-8rjr-v5mc (GitHub-reviewed advisory GHSA-3fpm-8rjr-v5mc lists affected ranges: Packagist wwbn/avideo >=0 <=26.0)
