CVE-2025-46821 is a medium-severity vulnerability affecting Envoy proxy versions prior to 1.34.1, 1.33.3, 1.32.6, and 1.31.8. It stems from an incorrect URI template matcher that excludes the '*' character, leading to a bypass of RBAC rules when uri_template permissions are configured. This allows an unauthenticated attacker to potentially bypass security controls with low attack complexity, resulting in a limited impact on integrity. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
