description

Shimmy versions through 2.6.4 contain an authentication flaw in the Inference API server component. A remote party may access affected API functionality without being authenticated when that interface is network-reachable.

mitigation

Upgrade Shimmy to version 2.6.5 or later. Until the upgrade is complete, limit access to the Inference API to trusted network paths and authenticated proxies.
