SCA: security update for composer/composer (GHSA-wg36-wvj6-r67p)

high Tenable Cloud Security Plugin ID 440406

Description

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

- Composer is a dependency manager for PHP. Versions 1.0 through 2.2.26 and 2.3 through 2.9.5 contain a
command injection vulnerability in the Perforce::generateP4Command() method, which constructs shell
commands by interpolating user-supplied Perforce connection parameters (port, user, client) without proper
escaping. An attacker can inject arbitrary commands through these values in a malicious composer.json
declaring a Perforce VCS repository, leading to command execution in the context of the user running
Composer, even if Perforce is not installed. VCS repositories are only loaded from the root composer.json
or the composer config directory, so this cannot be exploited through composer.json files of packages
installed as dependencies. Users are at risk if they run Composer commands on untrusted projects with
attacker-supplied composer.json files. This issue has been fixed in Composer 2.2.27 (2.2 LTS) and 2.9.6
(mainline). (CVE-2026-40176)

Solution

Update the composer/composer library and its related packages to version 2.2.27 or later.
