How to fix?

Upgrade Chainguard mise to version 2026.5.8-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream mise package and not the mise package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

Improper verification of cryptographic signature uniqueness in delegated role validation in awslabs/tough before tough-v0.22.0 allows remote authenticated users to bypass the TUF signature threshold requirement by duplicating a valid signature, causing the client to accept forged delegated role metadata.

We recommend you upgrade to tough-v0.22.0 / tuftool-v0.15.0.
