Description
Summary
This advisory addresses two critical security vulnerabilities present in Mautic versions before 5.2.3. These vulnerabilities could be exploited by authenticated users.
-
Remote Code Execution (RCE) via Asset Upload: A Remote Code Execution vulnerability has been identified in the asset upload functionality. Insufficient enforcement of allowed file extensions allows an attacker to bypass restrictions and upload executable files, such as PHP scripts.
-
Path Traversal File Deletion: A Path Traversal vulnerability exists in the upload validation process. Due to improper handling of path components, an authenticated user can manipulate the file deletion process to delete arbitrary files on the host system.
Mitigation
Please update to 5.2.3 or later.
Workarounds
None

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 5.2.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-73gx-x7r9-77x2 is resolved across your whole dependency graph.
Workarounds
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
