## What is CVE-2025-25207?

CVE-2025-25207 is a medium-severity denial of service vulnerability in Red Hat Connectivity Link 1, published on 9 Jun 2025. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

The Authorino service in the Red Hat Connectivity Link is the authorization service for zero trust API security. Authorino allows the users with developer persona to add callbacks to be executed to HTTP endpoints once the authorization process is completed. It was found that an attacker with developer persona access can add a large number of those callbacks to be executed by Authorino and as the authentication policy is enforced by a single instance of the service, this leada to a Denial of Service in Authorino while processing the post-authorization callbacks.

Weakness: CWE-770 (Allocation of Resources Without Limits or Throttling)

What it is: CVE-2025-25207 is a medium-severity denial of service vulnerability in Red Hat Connectivity Link 1, published on 9 Jun 2025. 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-2025-25207 in the wild and no public exploit code.

Affected packages and fixed versions:
- github.com/kuadrant/authorino (Go): affected all versions; no fix listed
- github.com/kuadrant/authorino (Go): affected all versions up to 0.20.0; no fix listed
- github.com/kuadrant/authorino (Go): affected all versions up to 0.20.0; 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.
