## What is CVE-2024-27905?

CVE-2024-27905 is a critical vulnerability in Apache Aurora, published on 27 Feb 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

** UNSUPPORTED WHEN ASSIGNED ** Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Aurora.

An endpoint exposing internals to unauthenticated users can be used as a "padding oracle" allowing an anonymous attacker to construct a valid authentication cookie. Potentially this could be combined with vulnerabilities in other components to achieve remote code execution.

As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users.

NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

Weakness: CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)

Check this codebase for CVE-2024-27905 and fix it if it is affected.

What it is: CVE-2024-27905 is a critical vulnerability in Apache Aurora, published on 27 Feb 2024. 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-2024-27905 in the wild and no public exploit code.

Affected product: Apache Aurora. 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.
