What is CVE-2026-92729?

The SigNoz product has a significant authorization flaw that occurs in versions 0.88.0 up to 0.141.0. This issue allows unauthenticated attackers to access trace-funnel analytics endpoints without proper authorization. As a result, malicious entities can submit arbitrary trace funnel definitions and extract sensitive information such as identifiers, service topology, and error activity from the trace analytics. The lack of an authorization wrapper on these endpoints presents a serious security risk, enabling unauthorized access to data that should be confidential.

Affected Version(s)

signoz 0.88.0 < 0.141.1
