Exploitability
Exploitation is relatively straightforward for authenticated users and requires an authenticated non-member with access to the affected migration scripts.
Blast radius
If exploited, this could result in unauthorized access to tenant resources and data, compromising the integrity and confidentiality of the system.
Detection
No reliable host or network indicator is derivable from the published description.
Prioritized remediation

NVD 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.
