## What is CVE-2026-77239?

CVE-2026-77239 is a high-severity missing authorization vulnerability in ArnasDon wacrm, published on 18 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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.
