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.

### Summary 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. ### Impact 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. ### 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](https://mautic.org/extended-long-term-support-elts/) page.* ### Workarounds There are no official workarounds. To mitigate this risk without upgrading, revoke campaign import permissions (`campaign:imports:create`) from non-administrative users.
