Description
In AWS Auth manager, the origin of the SAML authentication has been used as provided by the client and not verified against the actual instance URL. This allowed to gain access to different instances with potentially different access controls by reusing SAML response from other instances.
You should upgrade to 9.22.0 version of provider if you use AWS Auth Manager.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for apache-airflow-providers-amazon, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update apache-airflow-providers-amazon to 9.22.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rv5f-ccpm-xjj4 is resolved across your whole dependency graph.
Workarounds
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
