Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Missing permission guards in ticket mutation views allowed unauthorized actors to alter ticket states, deliver tickets, or close them without validation. Sibling APIs must comprehensively verify user access and state transitions prior to performing ticket lifecycle actions.
Auth Bypass: Incomplete tenant-isolation filtering on account, role, and membership queries allowed cross-tenant data access. Developers must explicitly validate HTTP-header-derived tenant scopes when retrieving or altering tenant associations.
Auth Bypass: Flaws in middleware and signature validation logic, such as incorrect Django HTTP header prefix lookups and database model object extraction issues, broke API-level authentication entirely. This allowed raw requests to bypass signature checks.
