AI-Generated

The evolution-api versions up to 2.3.7 are vulnerable due to an incorrect array comparison in the metricsIPWhitelist middleware, which allows unauthenticated access to the /metrics endpoint. This flaw enables attackers to bypass IP whitelist protections, potentially exposing sensitive information such as server version, database client name, and configured server URL. Organizations using this API should prioritize remediation to prevent unauthorized access to critical metrics.
