CVE-2026-77239
HighCVSS 8.1Summary
A vulnerability in WACRM (self-hostable CRM template for WhatsApp) in version 0.7.0 and earlier affects flow and automation write routes that authenticate account viewers but do not enforce the agent role before using a service-role database client that bypasses row-level security. A viewer can create, edit, activate, or delete flows and create active automations and trigger outbound WhatsApp actions without the required role.
Risk Assessment
Unauthorized users can make unauthorized workflow changes, delete flows, or send WhatsApp messages, compromising data integrity and confidentiality.
Recommendation
Apply the fix from commit 03e851bea56dcf6bb21ff1b80ba531372bf3269f or update WACRM to a version containing this fix. Additionally, enforce roles at the application level.
Other vulnerabilities in WACRM
See all- CVE-2026-77240Critical
WACRM 0.7.0 and earlier has vulnerabilities: row-level security policies allow authenticated users to modify their own role and account ID, enabling privilege escalation and cross-tenant movement. Additionally, match_ai_knowledge_fts and match_ai_knowledge_semantic run as SECURITY DEFINER with no account membership check, allowing non-members to read another tenant's knowledge chunks.
- CVE-2026-67530Medium
WACRM 0.7.0 and earlier allows an authenticated user with automation privileges to submit an arbitrary webhook URL that the server fetches without SSRF protection, enabling requests to private, loopback, link-local, or cloud metadata addresses.
- CVE-2026-49141High
Authorization bypass vulnerability in the WACRM automation engine prior to commit 73041bf. An authenticated attacker can access and modify contacts belonging to other tenants by supplying an arbitrary caller-controlled contact_id in a POST request without tenant ownership verification. The attacker can exploit a service-role client that bypasses row-level security to modify victim contact fields (name, email, company) across tenant boundaries using only a known contact UUID.
Original NVD description (English source)
WACRM is a self-hostable CRM template for WhatsApp. In version 0.7.0 and earlier, WACRM flow and automation write routes authenticate account viewers but do not enforce the agent role before using a service-role database client that bypasses row-level security. In src/app/api/flows/[id]/route.ts, src/app/api/flows/[id]/activate/route.ts, and src/app/api/flows/route.ts, a viewer can create, edit, activate, or delete flows because membership-only checks are followed by service-role writes. In src/app/api/automations/route.ts and src/app/api/automations/engine/route.ts, a viewer can create active automations and trigger outbound WhatsApp actions without the role required by the underlying write policies. This can permit unauthorized workflow changes, destructive flow deletion, and outbound actions from a role intended to be read-only. This vulnerability is fixed with commit 03e851bea56dcf6bb21ff1b80ba531372bf3269f.
