## What is CVE-2026-47136?

CVE-2026-47136 is a medium-severity vulnerability in rustfs, published on 28 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, the RustFS console endpoint GET /rustfs/console/license returns parsed license metadata without requiring authentication. The endpoint is registered on the console listener and returns JSON containing license information such as the license subject and expiration timestamp. Any client that can reach the console listener can query this endpoint without credentials. This vulnerability is fixed in 1.0.0-beta.2.

Weakness: CWE-306 (Missing Authentication for Critical Functionality), CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)

Check this codebase for CVE-2026-47136 and fix it if it is affected.

What it is: CVE-2026-47136 is a medium-severity vulnerability in rustfs, published on 28 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-47136 in the wild and no public exploit code.

Affected product: rustfs. 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.
