GHSA-qjx3-2g35-6hv8
HIGHGHSA-qjx3-2g35-6hv8 is a high-severity (CVSS 8.3) Incorrect Default Permissions vulnerability in mautic/core. O3 Security confirms whether GHSA-qjx3-2g35-6hv8 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Mautic Sensitive Data Exposure due to inadequate user permission settings
Blast Radius
mautic/core🐘mautic/coreReal-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
Impact
Prior to the patched version, logged in users of Mautic are able to access areas of the application that they should be prevented from accessing.
Users could potentially access sensitive data such as names and surnames, company names and stage names.
Patches
Update to 4.4.12 and 5.0.4
Workarounds
No

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mautic/core. 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 mautic/core to 4.4.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qjx3-2g35-6hv8 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-qjx3-2g35-6hv8 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-qjx3-2g35-6hv8. 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-qjx3-2g35-6hv8 in your dependencies?
O3 detects GHSA-qjx3-2g35-6hv8 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
