Description
SigNoz through 0.130.1 contains a broken access control vulnerability that allows authenticated users to access other organizations' alert rules by supplying a target rule UUID, as the alert rule store predicates fail to filter by organization ID. Attackers can read, edit, and delete alert rules belonging to other organizations by exploiting the missing tenant isolation check, bypassing multi-tenant access controls.
