CVE-2026-116812 · Severity: medium · CVSS 6.5 · Published 2026-10-27

OpenPanel is an analytics platform that uses ClickHouse for data queries. A SQL injection vulnerability in the cohort preview feature allows authenticated users with read access to inject malicious SQL code through profile filter column names, potentially exposing other tenants' data. An attacker can craft a filter that extracts sensitive information from the shared ClickHouse database across different customers.

## How to fix


Apply the PROFILE_COLUMNS allowlist used by the profileColumnSql function to profileColumnAccess, rejecting any column identifier not on the allowlist.

## Technical details

The vulnerability exists in the profileColumnAccess function in cohort.service.ts, which fails to allowlist or escape profile column identifiers before splicing them into SQL queries (argMax, cityHash64, and comparison clauses). An authenticated project-read member can inject a subquery via the cohort.preview endpoint to escape the outer project_id scope and read other tenants' data. The filter value is properly escaped, but the column identifier is not, creating an SQL injection sink in identifier context.
