Moby is an open source container framework. Prior to version 29.3.1, a security vulnerability has been detected that allows plugins privilege validation to be bypassed during docker plugin install. Due to an error in the daemon's privilege comparison logic, the daemon may incorrectly accept a privilege set that differs from the one approved by the user. Plugins that request exactly one privilege are also affected, because no comparison is performed at all. This issue has been patched in version 29.3.1.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-050390 advisory.

Tenable has extracted the preceding description block directly from the Fedora security advisory.

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

The version of the Docker Engine installed on the remote host is prior to 29.3.1. It is therefore affected by multiple vulnerabilities:

  - CVE-2026-34040: AuthZ plugin authorization bypass vulnerability. Authorization plugins could be bypassed     under specific conditions, potentially allowing unauthorized access.

  - CVE-2026-33997: Plugin privilege validation bypass vulnerability in 'docker plugin install' command.
    A flaw in privilege validation could be partially bypassed, potentially leading to unauthorized privilege     escalation.

  - CVE-2026-33748: BuildKit Git URL validation vulnerability. Insufficient validation of Git URL '#ref:subdir'     fragments could allow access to files outside the intended repository scope, leading to unauthorized     information disclosure.

  - CVE-2026-33747: BuildKit arbitrary file write vulnerability. An untrusted frontend could cause files to be     written outside the BuildKit state directory, potentially allowing local privilege escalation or unauthorized     file writes.

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.

  - Moby is an open source container framework. Prior to version 29.3.1, a security vulnerability has been     detected that allows plugins privilege validation to be bypassed during docker plugin install. Due to an     error in the daemon's privilege comparison logic, the daemon may incorrectly accept a privilege set that     differs from the one approved by the user. Plugins that request exactly one privilege are also affected,     because no comparison is performed at all. This issue has been patched in version 29.3.1. (CVE-2026-33997)

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

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