### 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 ### Details At line 44-48 of `cloneServer.json.php` (pre-fix): ```php if (!empty($_GET['deleteDump'])) { $resp->error = !unlink("{$clonesDir}{$_GET['deleteDump']}"); $resp->msg = "Delete Dump {$_GET['deleteDump']}"; die(json_encode($resp)); } ``` No `basename()`, no `realpath()` check, no path traversal filtering. `$_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 ```python """ CVE-2026-33293 - AVideo CloneSite Path Traversal """ import sys import os VULN_SRC = os.path
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. FIRST EPSS
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
