CVE-2026-116818 Details
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.
A ClickHouse SQL injection vulnerability has been identified in OpenPanel versions prior to 3.0.0. This vulnerability allows remote attackers to execute arbitrary SQL commands by injecting SQL through the projectId parameter of the /live/visitors/:projectId WebSocket. The injection is possible because the WebSocket handler does not perform session or project-access checks, leaving it unauthenticated. Exploitation of this vulnerability could lead to unauthorized access to other tenants' events and profiles.
To address this vulnerability, update OpenPanel to version 3.0.0 or later, where this issue has been fixed. Additionally, ensure that the ClickHouse client is configured to use a read-only, single-statement-constrained user.
