SCA: security update for github.com/distribution/distribution/v3, github.com/docker/distribution (GHSA-685w-q87j-wqw3)

medium Tenable Cloud Security Plugin ID 474711

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Distribution is a toolkit to pack, ship, store, and deliver container content. Prior to 3.1.2,
 registry/client.(*manifests).Get() reads a manifest returned for a digest-pinned request and passes it to
 distribution.UnmarshalManifest without hashing the body against the requested digest, allowing a malicious
 or intercepted registry response to substitute attacker-chosen manifest content even when Docker-Content-
 Digest claims the requested value. The bundled pull-through proxy in registry/proxy/proxymanifeststore.go
 can cache and re-serve the substituted manifest. This issue is fixed in version 3.1.2. (CVE-2026-85747)

Solution

Update the github.com/distribution/distribution/v3 library and its related packages to version 3.1.2 or later.
