SCA: security update for froxlor/froxlor (GHSA-mq5v-pxpm-8jw2)

high Tenable Self-Hosted Container Security Plugin ID 442490

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Froxlor is open source server administration software. Version 2.3.6 contains a symlink-following flaw in
the root-owned SSH key synchronization path used for customer FTP users. The provisioning code appends
public keys to `~/.ssh/authorized_keys` under a customer-controlled home directory without verifying that
the target path is not a symbolic link. If an attacker controls a shell-enabled customer account and can
modify files inside the assigned home directory, the attacker can replace `~/.ssh/authorized_keys` with a
symlink to `/root/.ssh/authorized_keys`. When Froxlor's privileged cron task later synchronizes SSH keys,
it appends the attacker-supplied key into root's authorized key file, resulting in root SSH access.
Version 2.3.7 contains a patch. (CVE-2026-41236)

Solution

Update the froxlor/froxlor library and its related packages to version 2.3.7 or later.
