• CVE-2026-34740: 0.33% estimated exploitation activity in the next 30 days; percentile 26.04 (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 EPG (Electronic Program Guide) link feature in AVideo allows authenticated users with upload permissions to store arbitrary URLs that the server fetches on every EPG page visit. The URL is validated only with PHP's FILTERVALIDATEURL, which accepts internal network addresses. Although AVideo has a dedicated isSSRFSafeURL() function for preventing SSRF, it is not called in this code path. This results in a stored server-side request forgery vulnerability that can be used to scan internal networks, access cloud metadata services, and interact with internal services. Details When a user adds or edits a video, the EPG link is stored via objects/videoAddNew.json.php:119: The only validation applied is FILTERVALIDATEURL, which accepts URLs targeting internal addresses such as http://127.0.0.1, http://169.254.169.254, or http://10.0.0.1. Later, when the EPG data is parsed, the stored URL is fetched server-side at objects/EpgParser.php:358: The filegetcontents() function follows…

# Patch Next advisory brief: CVE-2026-34740

Advisory: AVideo: Stored SSRF via Video EPG Link Missing isSSRFSafeURL() Validation
IDs: CVE-2026-34740, GHSA-x5vx-vrpf-r45f
Record: https://patchnext.com/advisories/cve-2026-34740 (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 <= 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-x5vx-vrpf-r45f (GitHub-reviewed advisory GHSA-x5vx-vrpf-r45f lists affected ranges: Packagist wwbn/avideo >=0 <=26.0)
