CVE-2026-9559

Path Traversal in Mautic 7 Campaign Import Enabling Remote Code Execution

Published May 29, 2026 CVSS 3.1 · 9.9 Critical EPSS < 1% KEV · Not listed
Description
A path traversal vulnerability exists in the campaign import feature of Mautic 7. When extracting uploaded ZIP files during campaign imports, a flaw in the validation logic allows file paths to escape the intended temporary directories. An authenticated user with campaign import privileges (campaign:imports:create) can write arbitrary PHP files to sensitive system directories. An attacker can exploit this to overwrite critical internal configuration or cache components, resulting in Remote Code Execution (RCE) under the context of the web server user.

Remediation

Vendor Workaround

There are no official workarounds. To mitigate this risk without upgrading, revoke campaign import permissions (campaign:imports:create) from non-administrative users.
