Description (CNA)
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.

A flaw was found in Moby, an open-source container framework. This vulnerability allows for a privilege validation bypass during `docker plugin install`. Due to an error in the daemon's privilege comparison logic, the system may incorrectly accept a plugin's requested privileges that differ from those approved by the user. This could lead to unauthorized privilege escalation for installed plugins.
