Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Ternary and equality logic within SQL RPC functions historically failed when handling NULL values (such as an unauthenticated user session). Because SQL operations involving NULL propagate as NULL rather than evaluating to false, anonymous callers could bypass user-ownership checks to manipulate arbitrary token states.
Auth Bypass: The use of an elevated service-role Supabase client in Edge Functions can bypass default Row-Level Security. Querying database tables using unvalidated user-supplied identifiers allows unauthorized data retrieval across tenants unless explicit identity verification is coded.
Denial of Service: Converting medium-to-large image uploads (e.g., payloads exceeding 32KB) into base64 format via direct stack-allocation methods like 'String.fromCharCode.apply' triggers call stack overflows, yielding denial of service on the Edge Function runtime.
