The `item_name` parameter, used to build the translation file's write path, does not sanitize directory traversal sequences such as `../`. This enables an authenticated user with `UPDATE`-level permissions on `admin.configuration.language` to write files outside the expected `templates/` directory, including to web‑accessible paths. Separately, the translation‑writing logic does not escape `\\` in user‑supplied values, allowing inputs to break out of the PHP string literal and inject executable code into the translation file. Chained together, these flaws allow a malicious PHP file to be written to a web-accessible path and executed with the web‑server’s privileges.","published":"2026-10-12T15:17:07.000Z","lastModified":"2026-10-15T18:17:22.000Z","status":"Deferred","sourceIdentifier":"cret@cert.org","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-94","CWE-434"],"affected":[],"epss":{"score":0.01051,"percentile":0.64122,"date":"2026-10-27","history":[{"date":"2026-10-13","score":0.00474,"percentile":0.3922}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (1.05%).
