GHSA-h37r-3qfp-73w6
SigNoz versions through 0.130.1 have a SQL injection vulnerability in the alert-history endpoints. Authenticated attackers can inject URL-encoded quotes into the rule ID path parameter, enabling arbitrary ClickHouse query execution. This allows attackers to read all stored traces, logs, and metrics or perform server-side request forgery via the url() function.
AI Analysis
Technical Summary
CVE-2026-57955 describes a SQL injection vulnerability in SigNoz up to version 0.130.1. The flaw arises from unsanitized interpolation of the rule ID path parameter in alert-history endpoints into ClickHouse queries. Authenticated attackers can exploit this by injecting URL-encoded quotes, leading to arbitrary query execution. This can expose sensitive telemetry data and enable server-side request forgery through abuse of the url() function within ClickHouse queries.
Potential Impact
An authenticated attacker can execute arbitrary ClickHouse queries, potentially accessing all stored traces, logs, and metrics. Additionally, the attacker can leverage the vulnerability to perform server-side request forgery, which may lead to further internal network attacks or data exfiltration. This compromises the confidentiality and integrity of the telemetry data stored by SigNoz.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the alert-history endpoints to trusted users only and monitor for suspicious activity involving rule ID parameters. Avoid exposing SigNoz services to untrusted networks.
