## What is CVE-2026-85201?

CVE-2026-85201 is a medium-severity denial of service vulnerability in Eclipse Ankaios, published on 7 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

In Eclipse Ankaios versions 0.1.0 through 1.0.1, the agent does not limit the length declared by a workload in a length-delimited protobuf message received through the Control Interface FIFO. A workload granted Control Interface access can specify an excessive message length, causing an unbounded memory allocation that may abort the Ankaios agent process. This results in loss of orchestration services for workloads managed by the affected agent.

Weakness: CWE-789 (Memory Allocation with Excessive Size Value), CWE-1284 (Improper Validation of Specified Quantity in Input)

What it is: CVE-2026-85201 is a medium-severity denial of service vulnerability in Eclipse Ankaios, published on 7 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-85201 in the wild and no public exploit code.

Affected product: Eclipse Ankaios. No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
