• CVE-2026-33681: 0.50% estimated exploitation activity in the next 30 days; percentile 42.98 (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 objects/pluginRunDatabaseScript.json.php endpoint accepts a name parameter via POST and passes it to Plugin::getDatabaseFileName() without any path traversal sanitization. This allows an authenticated admin (or an attacker via CSRF) to traverse outside the plugin directory and execute the contents of any install/install.sql file on the filesystem as raw SQL queries against the application database. Details The vulnerable data flow: 1. Entry point — objects/pluginRunDatabaseScript.json.php:21: 2. "Sanitization" — objects/plugin.php:343-354: 3. The "fix" — plugin/AVideoPlugin.php:3184-3190: 4. SQL execution — objects/pluginRunDatabaseScript.json.php:24-36: The sibling endpoint pluginRunUpdateScript.json.php correctly routes through AVideoPlugin::loadPlugin() which sanitizes the name with pregreplace('/[^0-9a-z]/i', '', $name) at AVideoPlugin.php:395. The vulnerable endpoint bypasses this sanitization entirely. Additionally, the endpoint lacks CSRF token validation. The…

# Patch Next advisory brief: CVE-2026-33681

Advisory: AVideo has Path Traversal in pluginRunDatabaseScript.json.php Enables Arbitrary SQL File Execution via Unsanitized Plugin Name
IDs: CVE-2026-33681, GHSA-3hwv-x8g3-9qpr
Record: https://patchnext.com/advisories/cve-2026-33681 (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: High (CVSS 7.2)
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-3hwv-x8g3-9qpr (GitHub-reviewed advisory GHSA-3hwv-x8g3-9qpr lists affected ranges: Packagist wwbn/avideo >=0 <=26.0)
