Vulnerability Title
WACRM: Database-layer authorization bypasses
Source: CVE Program / CVE List V5
Vulnerability Description
WACRM is a self-hostable CRM template for WhatsApp. In version 0.7.0 and earlier, the profiles_update row-level security policy in supabase/migrations/017_account_sharing.sql permits authenticated users to modify their own account_role and account_id, allowing a viewer to self-promote or move into another tenant and then access or modify tenant resources. Separately, match_ai_knowledge_fts and match_ai_knowledge_semantic in supabase/migrations/030_ai_knowledge.sql run as SECURITY DEFINER, accept a caller-controlled p_account_id, and omit an is_account_member check, allowing an authenticated non-member to read another tenant's knowledge-base chunks. This vulnerability is fixed with commit e01f7ed37184f972ace8fb2da5c3e37e56a6050f.
