Real-World Exposure

Description
Impact
The logic in place to facilitate the update process via the user interface lacks access control to verify if permission exists to perform the tasks. Prior to this patch being applied it might be possible for an attacker to access the Mautic version number or to execute parts of the upgrade process without permission. As upgrading in the user interface is deprecated, this functionality is no longer required.
Patches
Upgrade to 4.4.13 or 5.1.1 or later.
Workarounds
None.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mautic/core-lib, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update mautic/core-lib to 4.4.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-x3jx-5w6m-q2fc 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.
