CVE-2026-67530: CWE-918: Server-Side Request Forgery (SSRF) in ArnasDon wacrm
WACRM is a self-hostable CRM template for WhatsApp. In 0.7.0 and earlier, the automation send_webhook action in src/lib/automations/engine.ts and its validation in src/lib/automations/validate.ts allowed an authenticated user with automation privileges to submit an arbitrary webhook URL that the server fetched without the existing isDeliverableUrl SSRF guard in src/lib/webhooks/ssrf.ts, allowing requests to private, loopback, link-local, or cloud metadata addresses such as the cloud metadata endpoint at 169.254.169.254. This vulnerability is fixed with commit 23838a9959550e975d732ae08a44a3a2f0cc084b.
AI Analysis
Technical Summary
The vulnerability exists in the automation send_webhook action and its validation in wacrm versions 0.7.0 and earlier. Authenticated users with automation privileges could submit webhook URLs that the server fetched without applying the isDeliverableUrl SSRF guard, enabling requests to private, loopback, link-local, or cloud metadata addresses such as 169.254.169.254. This SSRF flaw was addressed and fixed by commit 23838a9959550e975d732ae08a44a3a2f0cc084b.
Potential Impact
An attacker with automation privileges can exploit this SSRF vulnerability to make the server perform unauthorized HTTP requests to internal network resources or cloud metadata services. This could lead to information disclosure or further internal network attacks. The CVSS score of 6.4 reflects a medium severity with low attack complexity and partial confidentiality and integrity impact.
Mitigation Recommendations
A fix is available and has been applied in the codebase as of commit 23838a9959550e975d732ae08a44a3a2f0cc084b.
