CVE-2026-57955 is a high-severity vulnerability rated 8.5/10 on the CVSS scale. 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.. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
