SigNoz through 0.130.1 contains a SQL injection vulnerability that allows authenticated attackers to execute arbitrary ClickHouse queries by injecting URL-encoded quotes into the rule ID path parameter of the alert-history endpoints. Attackers can manipulate the unsanitized rule ID interpolated into ClickHouse queries to read all stored traces, logs, and metrics, or abuse the url() function to perform server-side request forgery.
