## What is CVE-2026-85747?

CVE-2026-85747 is a medium-severity vulnerability in distribution, published on 13 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

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.

Weakness: CWE-354 (Improper Validation of Integrity Check Value)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2026-85747 and fix it if it is affected.

What it is: CVE-2026-85747 is a medium-severity vulnerability in distribution, published on 13 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-85747 exists.

Affected packages and fixed versions:
- github.com/distribution/distribution/v3 (Go): affected all versions; fixed in 3.1.2
- github.com/distribution/distribution/v3 (Go): affected all versions; fixed in 3.1.2
- distribution (Bitnami): affected all versions; fixed in 3.1.2
- github.com/docker/distribution (Go): affected all versions up to 2.8.3; no fix listed
- github.com/docker/distribution (Go): affected all versions up to 2.8.3; no fix listed

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
