SigNoz 0.130.1 - SQL Injection in Alert History Endpoints via Rule ID Parameter

Assigner: VulnCheck
Reserved: 26.06.2026 Published: 29.06.2026 Updated: 29.06.2026

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.
