CVE-2024-23323 is a medium-severity vulnerability affecting Envoy proxy versions prior to 1.29.1, 1.28.1, 1.27.3, and 1.26.7. It stems from inefficient regex compilation for each request when multiple routes use regex matchers, leading to high CPU utilization and increased latency. The attack vector is network-based with low complexity, requiring no user interaction or privileges, and its impact is limited to availability. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
