GHSA-frf7-jhp9-jxm6
Fix: mantisbt/mantisbt@69e0180GHSA-frf7-jhp9-jxm6 is a CWE-284 vulnerability in mantisbt/mantisbt. O3 Security confirms whether GHSA-frf7-jhp9-jxm6 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
MantisBT Vulnerable to Privilege Escalation from Manager to Administrator
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
Insufficient access control checks in ProjectUsersAddCommand (used in manage_proj_user_add.php and REST API endpoint PUT /project/{id}/users) allows users having manage_project_threshold access level (manager by default) to grant project-level administrator access to any user (including themselves) in any Project they have manager rights in.
The normal project-user add form does restrict the selectable access levels to the actor's own project role or below. However, the backend handler still accepts a forged higher access_level value and writes it.
Impact
Privilege escalation.
The consequences of the privilege escalation are not as bad as it may sound, because having administrator access at Project level is effectively not very different from being manager, it does not actually give administrator privileges on the whole MantisBT instance. In particular, it does not let the upgraded user delete the Project or grant them any access to global administrative functions such as managing Users, Projects, Plugins, Custom Fields, etc.

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-frf7-jhp9-jxm6 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-frf7-jhp9-jxm6 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-frf7-jhp9-jxm6. 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-frf7-jhp9-jxm6 in your dependencies?
O3 detects GHSA-frf7-jhp9-jxm6 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
