A security vulnerability has been identified in mailcow affecting versions prior to 2024-04. This vulnerability is a combination of path traversal and arbitrary code execution, specifically targeting the `rspamd_maps()` function. It allows authenticated admin users to overwrite any file writable by the www-data user by exploiting improper path validation. The exploit chain can lead to the execution of arbitrary commands on the server. Version 2024-04 contains a patch for the issue.","published":"2024-04-04T21:15:17.000Z","lastModified":"2026-06-17T07:26:39.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":6.2,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:L"},"cwe":["CWE-22"],"affected":["mailcow/mailcow\\"],"epss":{"score":0.27346,"percentile":0.98064,"date":"2026-11-03","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 27.3%, higher than 98% of all known CVEs.
