CVE-2026-33997

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.

Summary
  • (es) Moby es un framework de contenedor de código abierto. Antes de la versión 29.3.1, se ha detectado una vulnerabilidad de seguridad que permite omitir la validación de privilegios de los plugins durante docker plugin install. Debido a un error en la lógica de comparación de privilegios del demonio, este puede aceptar incorrectamente un conjunto de privilegios que difiere del aprobado por el usuario. Los plugins que solicitan exactamente un privilegio también se ven afectados, porque no se realiza ninguna comparación en absoluto. Este problema ha sido parcheado en la versión 29.3.1.
