Vulnerability AssessmentAI

Risk Assessment	The vulnerability presents moderate real-world risk based on converging signals. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An authenticated Chatwoot user (such as a customer service agent or low-privileged admin account) creates or modifies a webhook trigger and supplies a malicious URL-for example, pointing to a private Kubernetes API endpoint, internal database management interface, or cloud metadata service. The Webhooks::Trigger function processes this URL without validation and the server makes an HTTP request to that destination on behalf of the attacker. …
Remediation	Immediate remediation requires upgrading Chatwoot to a patched version beyond 4.11.2 when available; monitor the official Chatwoot repository and release notes for security updates addressing this SSRF. … Detailed patch versions, workarounds, and compensating controls in full report.
