OpenPanel versions before 3.0.0 are affected, specifically the cohort preview feature that handles profile filters. A user with project-read access can inject SQL through filter column names, which could let them read other tenants' analytics data stored in ClickHouse.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Openpanel-dev openpanel: fixed in 3.0.0

## Description

OpenPanel before 3.0.0 contains a sql injection vulnerability in profileColumnAccess in cohort.service.ts that allows project-read members to inject SQL by supplying unescaped profile filter column names. Attackers can submit a cohort.preview filter whose name contains a subquery spliced into argMax, cityHash64, or comparison clauses to read other tenants' ClickHouse data.
