SCA: security update for ansible-jailexec (GHSA-cxgv-hp74-jj7r)

high Tenable Cloud Security Plugin ID 445897

Description

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

 - Ansible FreeBSD Jail Connection Plugin is an Ansible connection plugin for FreeBSD Jails via jexec.
 Through version 1.3.0, the jailexec connection plugin's put_file resolved a transfer's destination to a
 path on the jail host ( + ) and ran mkdir -p and mv there as root on the host. Those commands follow
 symbolic links, and the path was operated on outside the jail, so a symlink existing inside the jail was
 followed by the host-side, root-privileged mv. A party controlling content inside a managed jail (the
 jail's root, or any process able to create a symlink in a directory an Ansible task later writes to) can
 therefore cause an arbitrary root-owned write on the host, outside the jail — a full jail escape.
 Arbitrary root-owned host writes are readily escalated to host compromise (e.g. cron, rc.d,
 authorized_keys). Preconditions for this vulnerability are that the operator runs a copy/template/fetch-
 style task (anything using put_file) against the jail, and the attacker can place a symlink inside the
 jail at or above the task's destination before the transfer runs. This issue has been fixed in version
 2.0.0. (CVE-2026-55074)

Solution

Update the ansible-jailexec library and its related packages to version 2.0.0 or later.
