GHSA-6p68-36m6-392r
MEDIUMphpMyFAQ Stored Cross-site Scripting at FAQ News Content
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Blast Radius
phpmyfaq/phpmyfaqReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
Summary
By manipulating the news parameter in a POST request, an attacker can inject malicious JavaScript code. Upon browsing to the compromised news page, the XSS payload triggers.
PoC
- Edit a FAQ news, intercept the request and modify the
newsparameter in the POST body with the following payload:%3cscript%3ealert('xssContent')%3c%2fscript%3e - Browse to the particular news page and the XSS should pop up.
Impact
This allows an attacker to execute arbitrary client side JavaScript within the context of another user's phpMyFAQ session
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | phpmyfaq/phpmyfaq | ≥ 3.2.5&&< 3.2.6 | 3.2.6 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for phpmyfaq/phpmyfaq. 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.
Fix
Update phpmyfaq/phpmyfaq to 3.2.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6p68-36m6-392r is resolved across your whole dependency graph.
Workarounds
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-6p68-36m6-392r 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-6p68-36m6-392r. 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-6p68-36m6-392r in your dependencies?
O3 detects GHSA-6p68-36m6-392r across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
