Moby has AuthZ plugin bypass when provided oversized request bodies

Summary

A security vulnerability has been detected that allows attackers to bypass authorization plugins (AuthZ) under specific circumstances. The base likelihood of this being exploited is low.

This is an incomplete fix for CVE-2024-41110.

Impact

If you don't use AuthZ plugins, you are not affected.

Using a specially-crafted API request, an attacker could make the Docker daemon forward the request to an authorization plugin without the body. The authorization plugin may allow a request which it would have otherwise denied if the body had been forwarded to it.

Anyone who depends on authorization plugins that introspect the request body to make access control decisions is potentially impacted.

Workarounds

If unable to update immediately:

  • Avoid using AuthZ plugins that rely on request body inspection for security decisions.
  • Restrict access to the Docker API to trusted parties, following the principle of least privilege.

Docker is a product for you to build, ship and run any application as a lightweight container.

Security Fix(es):

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)
