• CVE-2026-41058: 0.47% estimated exploitation activity in the next 30 days; percentile 40.63 (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 incomplete fix for AVideo's CloneSite deleteDump parameter does not apply path traversal filtering, allowing unlink() of arbitrary files via ../../ sequences in the GET parameter. Affected Package - Ecosystem: Other - Package: AVideo - Affected versions: < commit 941decd6d19e - Patched versions: = commit 941decd6d19e Details At line 44-48 of cloneServer.json.php (pre-fix): No basename(), no realpath() check, no path traversal filtering. $GET['deleteDump'] is concatenated directly with $clonesDir. The vulnerable code has zero protection against path traversal: - No basename() to strip directory components - No realpath() to validate the final path - No check that resolved path is within $clonesDir - No ../ sanitization - Additionally, exec() calls with mysqldump pass credentials on the command line PoC Steps to reproduce: 1. git clone https://github.com/WWBN/AVideo /tmp/AVideotest 2. cd /tmp/AVideotest && git checkout 941decd6d19e2e694acb75e86317d10fbb560284~1 3. python3…

# Patch Next advisory brief: CVE-2026-41058

Advisory: WWBN AVideo has an incomplete fix for CVE-2026-33293: Path Traversal
IDs: CVE-2026-41058, GHSA-5879-4fmr-xwf2
Record: https://patchnext.com/advisories/cve-2026-41058 (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 6.9)
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-5879-4fmr-xwf2 (GitHub-reviewed advisory GHSA-5879-4fmr-xwf2 lists affected ranges: Packagist wwbn/avideo >=0 <=29.0)
