CVE-2026-41231 is a high-severity flaw (CVSS 7.5) affecting froxlor. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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 symlin
