Deskripsi (NVD)

Higress before 2.2.4 panics when processing a Cookie header segment without an equals sign, causing the plugin wrapper to recover and return a continue action that bypasses AI token rate limiting. Unauthenticated attackers can craft a malformed Cookie header to skip rate limit checks and exceed thresholds intended to restrict costly model backend calls.
