GHSA-q747-c74m-69pr is a medium-severity (CVSS 5.4) CWE-201 vulnerability in mantisbt/mantisbt. O3 Security confirms whether GHSA-q747-c74m-69pr is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
MantisBT lacks verification when changing a user's email address
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
When a user edits their profile to change their e-mail address, the system saves it without validating that it actually belongs to the user.
Impact
This could result in storing an invalid email address, preventing the user from receiving system notifications.
Notifications sent to another person's email address could lead to information disclosure.
Patches
Fixed in 2.27.2.
Workarounds
None

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 2.27.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-q747-c74m-69pr 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-q747-c74m-69pr 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-q747-c74m-69pr. 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-q747-c74m-69pr in your dependencies?
O3 detects GHSA-q747-c74m-69pr across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
