CVE-2026-63080

Aptabase through commit 5a89368 contains a SQL injection vulnerability in the ClickHouse query backend that allows authenticated attackers to read event data across all tenants by injecting unsanitized filter parameters into Liquid SQL templates. Attackers can supply malicious values through EventName, CountryCode, OsName, DeviceModel, AppVersion, or SessionId parameters to inject a UNION ALL statement that bypasses the app_id tenant isolation filter across thirteen of the fifteen stats API endpoints.
