CVE-2026-3958Public exploitNetwork attack vector

Authenticated internal network access via unvalidated webhook URL

Published Mar 11, 2026 · Updated Mar 11, 2026

SSRF in WoahAI ListSync 0.6.0 through 0.6.6 allows remote authenticated users to make the server request arbitrary URLs. The notification-test handler passes the JSON webhook_url value directly to DiscordWebhook or requests.post without URL validation or an allowlist. Low-privileged API access is required; exploitation enables internal service probing or requests to metadata endpoints.
