0 CVE-2023-4853 is a high-severity vulnerability in Red Hat Openshift Serverless 1 on RHEL 8 caused by improper input sanitization in Quarkus HTTP security policies. The flaw allows certain character permutations in requests to bypass security policy checks, potentially granting unauthorized access to protected endpoints and enabling denial of service. Exploitation requires no authentication or user interaction but has a high attack complexity. The vulnerability impacts confidentiality, integrity, and availability of affected systems. No known exploits are currently reported in the wild. European organizations using Openshift Serverless on RHEL 8 should prioritize patching and implement strict input validation and network segmentation to mitigate risk. Countries with significant Red Hat and Openshift adoption, such as Germany, France, and the UK, are most likely to be affected.
