Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
SSRF: The SDK makes outbound HTTP requests to callback URLs derived from incoming events; without strict validation, an attacker can supply a URL pointing to internal services, enabling blind SSRF.
Auth Bypass: The origin allow-list check used a prefix match, so a crafted origin like 'evil-example.com' could pass a check for 'example.com', allowing unauthorized senders to trigger callbacks.
