  "title": "Argument-limit rule bypass in Coraza v3",
  "summary": "Coraza v3 before 3.8.1 may silently exclude request arguments when argument limits are reached, allowing rules that inspect argument collections to miss attacker-controlled input. URL-encoded POST requests may also exceed the intended argument cap; exposure requires deployments that accept such requests and rely on argument-targeted WAF rules.",
  "mitigation": "Upgrade github.com/corazawaf/coraza/v3 to 3.8.1. Until upgraded, reject requests whose GET, POST, or path argument counts reach the configured argument limit, with thresholds matching SecArgumentsLimit.",
