Description
Summary
An authenticated Remote Code Execution (RCE) vulnerability was identified in AVideo related to the plugin upload/import functionality.
The issue allowed an authenticated administrator to upload a specially crafted ZIP archive containing executable server-side files. Due to insufficient validation of extracted file contents, the archive was extracted directly into a web-accessible plugin directory, allowing arbitrary PHP code execution.
Vulnerability Type
- Remote Code Execution (RCE)
- CWE-434: Unrestricted Upload of File with Dangerous Type
Affected Versions
- All versions up to and including 22.x.
Fixed Version
- A fix is expected to be released in version 23.
Root Cause
The system validated only the ZIP extension of uploaded plugin packages but did not enforce a strict allowlist of file types within the archive. Extracted files were placed directly in a web-accessible directory without preventing execution of server-side scripts.
Impact
An authenticated administrator could execute arbitrary code on the server, resulting in full system compromise, including:
- Confidentiality loss
- Integrity loss
- Availability impact
Remediation
Upgrade immediately to AVideo version 23 or later.
Version 23 introduces improved validation and secure handling of plugin extraction.
Workarounds
If upgrade is not immediately possible:
- Disable plugin upload/import functionality.
- Configure the web server to prevent execution of PHP files inside plugin upload directories.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for wwbn/avideo. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of wwbn/avideo has shipped for GHSA-v8jw-8w5p-23g3 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-v8jw-8w5p-23g3 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-v8jw-8w5p-23g3. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-v8jw-8w5p-23g3 in your dependencies?
O3 detects GHSA-v8jw-8w5p-23g3 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
