• CVE-2026-35449: 0.34% estimated exploitation activity in the next 30 days; percentile 28.11 (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 install/test.php diagnostic script has its CLI-only access guard disabled by commenting out the die() statement. The script remains accessible via HTTP after installation, exposing video viewer statistics including IP addresses, session IDs, and user agents to unauthenticated visitors. Details The disabled guard at install/test.php:5-7: The script also enables verbose error reporting: It then queries VideoStatistic::getLastStatistics() and outputs the result via vardump(): The VideoStatistic object contains: ip (viewer IP address), sessionid, useragent, usersid, and JSON metadata. The displayerrors=1 setting also leaks internal filesystem paths in any PHP warnings. The install/ directory is not restricted by .htaccess (it only disables directory listing via Options -Indexes) and no web server rules block access to individual PHP files in this directory.

# Patch Next advisory brief: CVE-2026-35449

Advisory: AVideo: Unauthenticated Information Disclosure via Disabled CLI Guard in install/test.php
IDs: CVE-2026-35449, GHSA-hg8q-8wqr-35xx
Record: https://patchnext.com/advisories/cve-2026-35449 (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 5.3)
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-hg8q-8wqr-35xx (GitHub-reviewed advisory GHSA-hg8q-8wqr-35xx lists affected ranges: Packagist wwbn/avideo >=0 <=26.0)
