{"id":"CVE-2026-41228","summary":"Froxlor has Local File Inclusion via path traversal in API `def_language` parameter that leads to Remote Code Execution","details":"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.","aliases":["GHSA-w59f-67xm-rxx7"],"modified":"2026-07-15T01:48:56.485469925Z","published":"2026-04-23T03:41:47.479Z","database_specific":{"cwe_ids":["CWE-98"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41228.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/froxlor/froxlor/releases/tag/2.3.6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41228.json"},{"type":"ADVISORY","url":"https://github.com/froxlor/froxlor/security/advisories/GHSA-w59f-67xm-rxx7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41228"},{"type":"FIX","url":"https://github.com/froxlor/froxlor/commit/bc5e6dbaa90e6f3573129da640595e8c770e1d0c"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/froxlor/froxlor","events":[{"introduced":"0"},{"fixed":"d32aa3567c8eb033bbc8667bfca2969f5cdb199f"},{"fixed":"bc5e6dbaa90e6f3573129da640595e8c770e1d0c"}],"database_specific":{"cpe":"cpe:2.3:a:froxlor:froxlor:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2.3.6"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["2.3.5","2.3.4","2.3.3","2.3.2","2.3.1","2.3.0","2.3.0-rc1","2.2.0-rc1","2.1.4","2.1.3","2.1.2","2.1.1","2.1.0","2.1.0-rc3","2.1.0-rc2","2.1.0-rc1","2.1.0-beta2","2.1.0-beta1","2.0.24","2.0.23","2.0.22","2.0.21","2.0.20","2.0.19","2.0.18","2.0.17","2.0.16","2.0.15","2.0.14","2.0.13","2.0.12","2.0.11","2.0.10","2.0.9","2.0.8","2.0.7","2.0.6","2.0.5","2.0.4","2.0.3","2.0.2","2.0.1","0.10.33","0.10.32","0.10.31","0.10.30","0.10.29.1","0.10.29","0.10.28","0.10.27","0.10.26","0.10.25","0.10.24","0.10.23.1","0.10.23","0.10.22","0.10.21","0.10.20","0.10.19","0.10.18","0.10.17","0.10.16","0.10.15","0.10.14","0.10.13","0.10.12","0.10.11","0.10.10","0.10.9","0.10.8","0.10.7","0.10.6","0.10.5","0.10.4","0.10.3","0.10.2","0.10.1","0.10.0","0.10.0-rc2","0.10.0-rc1","0.9.39.5","0.9.39.4","0.9.39.3","0.9.39.2","0.9.39.1","0.9.39","0.9.38.8","0.9.38.7","0.9.38.6","0.9.38.5","0.9.38.4","0.9.38.3","0.9.38.2","0.9.38.1","0.9.38","0.9.38-rc2","0.9.38-rc1","0.9.37","0.9.37-rc1","0.9.36","0.9.35.1","0.9.35","0.9.35-rc1","0.9.34.2","0.9.34.1","0.9.33-rc3","0.9.33-rc2","0.9.33-rc1","0.9.32","0.9.32-rc2","0.9.32-rc1","0.9.31-rc1","0.9.30","0.9.30-rc1","0.9.29","0.9.29-rc1","0.9.28.1","0.9.28","0.9.28-rc1","0.9.27","0.9.27-rc1","0.9.26","0.9.26-rc1","0.9.25","0.9.25-rc1","0.9.24","0.9.24-rc1","0.9.23","0.9.23-rc1","0.9.22","0.9.22-rc1","0.9.21","0.9.20.1","0.9.20","0.9.19","0.9.18.1","0.9.18"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-41228.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
