GHSA-93x3-m7pw-ppqm
HIGHMantis Bug Tracker (MantisBT) allows user account takeover in the signup/reset password process
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
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 in the registration and password reset process allows an attacker to reset another user's password and takeover their account, if the victim has an incomplete request pending.
The exploit is only possible while the verification token is valid, i.e for 5 minutes after the confirmation URL sent by e-mail has been opened, and the user did not complete the process by updating their password.
A brute-force attack calling account_update.php with increasing user IDs is possible.
Impact
A successful takeover would grant the attacker full access to the compromised account, including sensitive information and functionalities associated with the account, the extent of which depends on its privileges and the data it has access to.
Patches
92d11a01b195a1b6717a2f205218089158ea6d00
Workarounds
Mitigate the risk by reducing the verification token's validity (change the value of the TOKEN_EXPIRY_AUTHENTICATED constant in constants_inc.php).

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 2.26.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-93x3-m7pw-ppqm 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-93x3-m7pw-ppqm 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-93x3-m7pw-ppqm. 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-93x3-m7pw-ppqm in your dependencies?
O3 detects GHSA-93x3-m7pw-ppqm across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
