CVE-2025-64522Public exploitNetwork attack vector

Authenticated internal-service access via unvalidated webhook URLs

Published Nov 10, 2025 · Updated Nov 12, 2025

SSRF in Charmbracelet Soft Serve before 0.11.1 allows remote authenticated users to access internal HTTP services through webhooks. The webhook creation and update paths accept an unvalidated destination URL, and delivery sends a server-side HTTP request without blocking private, loopback, link-local, or metadata addresses. Repository-administrator privileges and a triggered webhook are required; responses stored in delivery logs can disclose internal data and cloud credentials.
