Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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::syncCodeBase() method, which appends the $sourceReference     parameter to a shell command without proper escaping, and additionally in the     Perforce::generateP4Command() method as in GHSA-wg36-wvj6-r67p / CVE-2026-40176, which interpolates user-     supplied Perforce connection parameters (port, user, client) from the source url field without proper     escaping. An attacker can inject arbitrary commands through crafted source reference or source url values     containing shell metacharacters, even if Perforce is not installed. Unlike CVE-2026-40176, the source     reference and url are provided as part of package metadata, meaning any compromised or malicious Composer     repository can serve package metadata declaring perforce as a source type with malicious values. This     vulnerability is exploitable when installing or updating dependencies from source, including the default     behavior when installing dev-prefixed versions. This issue has been fixed in Composer 2.2.27 (2.2 LTS) and     2.9.6 (mainline). If developers are unable to immediately update, they can avoid installing dependencies     from source by using --prefer-dist or the preferred-install: dist config setting, and only use trusted     Composer repositories as a workaround. (CVE-2026-40261)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 7a7a17b2-381c-11f1-a663-10ffe07f9334 advisory.

    Composer project reports:
    Fixed command injection via malicious Perforce reference (GHSA-gqw4-4w2p-838q / CVE-2026-40261)     Fixed command injection via malicious Perforce repository definition (GHSA-wg36-wvj6-r67p /     CVE-2026-40176)
