Users should monitor Red Hat advisories for updates. Since this is a resource exhaustion issue triggered by malicious HTTP responses, consider limiting exposure to untrusted or malicious servers and applying network-level controls to restrict communications to trusted endpoints. Engage with Red Hat support or a Technical Account Manager for tailored guidance. Avoid deploying vulnerable versions in high-risk environments until a fix is released.

Description

The RHTAS Operator can be used with OpenShift Container Platform 4.16, 4.17, 4.18, 4.19, and 4.20
