{"id":"CVE-2026-41231","aliases":["GHSA-75h4-c557-j89r"],"url":"https://o3.security/vulnerability/CVE-2026-41231","summary":"Froxlor has Incomplete Symlink Validation in DataDump.add() that Allows Arbitrary Directory Ownership Takeover via Cron","details":"Froxlor is open source server administration software. Prior to version 2.3.6, `DataDump.add()` constructs the export destination path from user-supplied input without passing the `$fixed_homedir` parameter to `FileDir::makeCorrectDir()`, bypassing the symlink validation that was added to all other customer-facing path operations (likely as the fix for CVE-2023-6069). When the ExportCron runs as root, it executes `chown -R` on the resolved symlink target, allowing a customer to take ownership of arbitrary directories on the system. Version 2.3.6 contains an updated fix.","published":"2026-04-23T03:52:42.587Z","modified":"2026-08-12T03:51:22.279975464Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.00414,"percentile":0.34109,"asOf":"2026-08-08"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"froxlor/froxlor","fixedVersion":"2.3.6"}],"fix":{"url":"https://github.com/froxlor/froxlor/commit/2987b0e8806ef12b532410050ad76d13d673a87d","label":"froxlor/froxlor@2987b0e"},"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-2026-41231.json"},{"type":"ADVISORY","url":"https://github.com/froxlor/froxlor/security/advisories/GHSA-75h4-c557-j89r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41231"},{"type":"FIX","url":"https://github.com/froxlor/froxlor/commit/2987b0e8806ef12b532410050ad76d13d673a87d"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:22.279975464Z"}}
