dCERT Flags vLLM Flaws and Spring Security Authentication Bypass
dCERT published two security advisories covering separate software risks: multiple vulnerabilities in vllm and a VMware Tanzu Spring Security flaw that can bypass security measures. The vllm advisory identifies more than one issue affecting the large language model serving software, while the Spring Security advisory warns that affected deployments may allow protections to be circumvented.
The notices indicate that organizations using either product should review the relevant dCERT advisories, determine exposure in their environments, and prioritize remediation. The Spring Security issue is especially significant for internet-facing or authentication-dependent applications because a bypass in security controls can undermine access restrictions, while the vllm findings raise concern for AI infrastructure operators running vulnerable versions in production or shared environments.
