CVE-2026-26309
Envoy CVE-2026-26309 describes an off-by-one write in Envoy::JsonEscaper::escapeString() that can corrupt std::string null-termination, causing undefined behavior and potentially crashes or out-of-bounds reads when treated as a C-string. Affected before 1.37.1, 1.36.5, 1.35.8, 1.34.13. The vulner...
CVE-2026-26308
Envoy is a high-performance edge/middle/service proxy. Prior to 1.37.1, 1.36.5, 1.35.8, and 1.34.13, the Envoy RBAC Role-Based Access Control filter contains a logic vulnerability in how it validates HTTP headers when multiple values are present for the same header name. Instead of validating eac...
CVE-2026-26308
Envoy CVE-2026-26308 affects the Envoy RBAC filter. The issue arises from how multiple HTTP header values are validated: instead of validating each value separately, Envoy concatenates all values into a single comma-separated string, allowing bypass of Deny rules under RBAC. Affects versions prio...

Envoy's global rate limit may crash when the response phase limit is enabled and the response phase request is failed directly
Summary At the rate limit filter, if we enabled the response phase limit with applyonstreamdone in the rate limit configuration and the response phase limit request fails directly, it may crash Envoy. Details When both the request phase limit and response phase limit are enabled, the safe gRPC...
