Severity by source

GHSA10.0CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H

Trivy's own label is CRITICAL. Rated critical by GHSA.

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.
