GHSA-6jh4-47v2-4g37
Fix: mantisbt/mantisbt@b1ebc57GHSA-6jh4-47v2-4g37 is a security vulnerability in mantisbt/mantisbt. O3 Security confirms whether GHSA-6jh4-47v2-4g37 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
MantisBT has Potential Referer-Based Reflected HTML Injection / XSS in Tag Update Page
Real-World Exposure
mantisbt/mantisbtReal-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
Improper escaping of the redirection page (retrieved from the request's Referer header) allows an attacker to inject HTML.
While this is generally not directly actionable as modern browsers will URL-encode special characters, on some specific server configurations this could poison the cache, leading to cross-site scripting.
Impact
Cross-site scripting (XSS).

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mantisbt/mantisbt. 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 mantisbt/mantisbt to 2.28.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6jh4-47v2-4g37 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-6jh4-47v2-4g37 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-6jh4-47v2-4g37. 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-6jh4-47v2-4g37 in your dependencies?
O3 detects GHSA-6jh4-47v2-4g37 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
