Brief Summary

“Docker’s default authorization model is all-or-nothing. Users with access to the Docker daemon can execute any Docker command. For greater access control, authorization plugins (AuthZ) can be used. These plugins approve or deny requests to the Docker daemon based on authentication and command context.

In 2018, a security issue was discovered where an attacker could bypass AuthZ plugins using a specially crafted API request. This could lead to unauthorized actions, including privilege escalation. Although this issue was fixed in Docker Engine v18.09.1 in January 2019, the fix was not carried forward to later versions, resulting in a regression.” - Docker Security Advisory: AuthZ Plugin Bypass Regression in Docker Engine | Docker
