CVE-2026-63080Public exploitNetwork attack vector

Cross-tenant event disclosure via Liquid SQL injection

Published Jul 21, 2026 · Updated Jul 21, 2026

SQL injection in Aptabase through commit 5a89368 allows remote authenticated users to read event data across all tenants via crafted filters. Thirteen of fifteen stats API endpoints render filter values into Liquid SQL templates without neutralization, allowing UNION ALL to bypass app_id tenant filtering. A valid user session is required; exploitation exposes other tenants' event data without reported modification or service interruption.
