GHSA-2jrw-c95w-h43g
HIGHGHSA-2jrw-c95w-h43g is a high-severity (CVSS 7.1) CWE-863 vulnerability in mautic/core. O3 Security confirms whether GHSA-2jrw-c95w-h43g is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

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.
How urgent is this, really
GHSA-2jrw-c95w-h43g plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 0 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Summary
An authorization bypass vulnerability exists in the Mautic 7 API v2 endpoints (utilizing API Platform). Under certain conditions, roles configured with owner-scope restrictions (such as viewown or editown) are not properly enforced. This allows low-privilege authenticated API users to bypass ownership-logic controls and access or modify resources belonging to other users.
Impact
Authenticated API users with limited roles can read or modify restricted resources—including reports, contacts, and companies—that they do not own and should not have access to. This bypasses structural tenant and privilege boundaries on the platform.
Patched Versions
This security issue has been addressed in the following release:
- 7.1.2
Note: Mautic 6.x, 5.x, and 4.x branches are not affected by this vulnerability. For general security support regarding legacy Mautic 4 releases, please refer to the ELTS page.
Workarounds
There are no official workarounds. To mitigate this issue without upgrading, temporarily revoke API credentials or narrow access permissions for any users whose roles rely on owner-scope permission containment.

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 7.1.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2jrw-c95w-h43g 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-2jrw-c95w-h43g 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-2jrw-c95w-h43g. 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-2jrw-c95w-h43g in your dependencies?
O3 detects GHSA-2jrw-c95w-h43g across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
