{"id":"CVE-2026-41228","state":"PUBLISHED","title":"Froxlor has Local File Inclusion via path traversal in API `def_language` parameter that leads to Remote Code Execution","description":"Froxlor is open source server administration software. Prior to version 2.3.6, the Froxlor API endpoint `Customers.update` (and `Admins.update`) does not validate the `def_language` parameter against the list of available language files. An authenticated customer can set `def_language` to a path traversal payload (e.g., `../../../../../var/customers/webs/customer1/evil`), which is stored in the database. On subsequent requests, `Language::loadLanguage()` constructs a file path using this value and executes it via `require`, achieving arbitrary PHP code execution as the web server user. Version 2.3.6 fixes the issue.","publishedAt":"2026-04-23T03:41:47.479Z","updatedAt":"2026-04-23T14:48:07.640Z","severity":{"score":10,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["froxlor froxlor"],"affected":[{"vendor":"froxlor","product":"froxlor","versions":[{"version":"< 2.3.6","status":"affected"}]}],"references":["https://github.com/froxlor/froxlor/security/advisories/GHSA-w59f-67xm-rxx7","https://github.com/froxlor/froxlor/commit/bc5e6dbaa90e6f3573129da640595e8c770e1d0c","https://github.com/froxlor/froxlor/releases/tag/2.3.6"],"weaknesses":["CWE-98"],"ingestedAt":"2026-10-29T20:11:57.932Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/41xxx/CVE-2026-41228.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-41228","state":"PUBLISHED","datePublished":"2026-04-23T03:41:47.479Z","dateUpdated":"2026-04-23T14:48:07.640Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-04-18T03:47:03.134Z"},"containers":{"cna":{"title":"Froxlor has Local File Inclusion via path traversal in API `def_language` parameter that leads to Remote Code Execution","descriptions":[{"lang":"en","value":"Froxlor is open source server administration software.
