Description
This security bulletin contains information about 1 security vulnerability.
1) Authentication Bypass by Alternate Name (CVE-ID: CVE-2025-8415)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to missing authentication in Cryostat HTTP API bound by default to 0.0.0.0 port 8181/tcp. A remote non-authenticated attacker within the cluster can under certain circumstances determine the internal Pod IP of the Cryostat container and sent HTTP requests directly to its API port, bypassing the openshift-oauth-proxy completely
