GHSA-7mqj-8gj2-cg59
Fix: mantisbt/mantisbt@5cb4b46GHSA-7mqj-8gj2-cg59 is a Cross-site Scripting (XSS) vulnerability in mantisbt/mantisbt. O3 Security confirms whether GHSA-7mqj-8gj2-cg59 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
MantisBT has Stored XSS on Move Attachments Admin Page
Exploitation Status
No confirmed exploitation observed yet
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

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.
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
Unescaped Project Name allows an attacker that can set it (which typically requires manager or administrator access level) to inject HTML in Move Attachments admin page.
Impact
Cross-site scripting (XSS). This is mitigated by Content Security Policy which restricts scripts execution.

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-7mqj-8gj2-cg59 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-7mqj-8gj2-cg59 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-7mqj-8gj2-cg59. 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-7mqj-8gj2-cg59 in your dependencies?
O3 detects GHSA-7mqj-8gj2-cg59 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
