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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/kuadrant/authorino, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of github.com/kuadrant/authorino for CVE-2025-25207. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
