## What is CVE-2025-54066?

CVE-2025-54066 is a medium-severity vulnerability in DIRACGrid diracx-web, published on 17 Jul 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

DiracX-Web is a web application that provides an interface to interact with the DiracX services. Prior to version 0.1.0-a8, an attacker can forge a request that they can pass to redirect an authenticated user to another arbitrary website. In the login page, DiracX-Web has a `redirect` field which is the location where the server will redirect the user. This URI is not verified, and can be an arbitrary URI. Paired with a parameter pollution, an attacker can hide their malicious URI. This could be used for phishing, and extract new data (such as redirecting to a new "log in" page, and asking another time credentials). Version 0.1.0-a8 fixes this vulnerability.

Weakness: CWE-601 (URL Redirection to Untrusted Site)

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.
