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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update mautic/core to 7.1.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-9808 is resolved across your whole dependency graph.
Workarounds
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
