Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Custom domain and subdomain routing is highly vulnerable to domain hijacking and unauthorized tenant resolution if host header ownership is not continuously validated against registered tenant metadata.
Reflected XSS: Markdown rendering with Rehype is a constant source of XSS vectors if allowlist configurations and element attribute controls (such as iframe style configurations or media attributes) are not rigorously tightened.
Auth Bypass: Dashboard routes are susceptible to unauthorized access and layout exposure if permissions are not strictly evaluated, or if client-side redirects fail to properly block the rendering of children elements when permissions are absent.
