This rule detects the authentication bypass vulnerability in Flowise <= 1.8.2 (CVE-2024-8181) by matching requests to the crafted endpoint
/api/v1/apikey?/api/v1/ping. The exploit abuses a malformed query string to bypass authentication and access sensitive API endpoints. The rule uses theURIzone with bothlowercaseandurldecodetransforms to ensure case-insensitive and encoded/decoded matching. Thecontainsmatch type is used to reliably detect the exploit pattern without false positives. The labels section includes the correct CVE, ATT&CK, and CWE references for classification. No additional zones or variables are needed, as the attack is specific to the malformed URI. All values are lowercase, and the rule avoids regex or unnecessary complexity, ensuring optimal detection with minimal false positives.
