OpenPanel before 3.0.0 Unauthenticated ClickHouse SQL Injection via /live/visitors WebSocket

Published Oct 26, 2026 · Updated Nov 8, 2026 · Assigned by VulnCheck

Description

OpenPanel before 3.0.0 contains an unauthenticated ClickHouse SQL injection vulnerability that allows remote attackers to inject SQL through the projectId parameter of the /live/visitors/:projectId WebSocket, which lacks session and project-access checks. Attackers can use UNION or boolean count oracles to read other tenants' events and profiles, and project members can similarly inject via the cohort.preview timeframe values.
