github.com/gotenberg/gotenberg/v8 is vulnerable to Server-Side Request Forgery (SSRF)
72
High Risk
This Affects:
github.com/gotenberg/gotenberg/v8TL;DR
An improper input validation issue in Gotenberg outbound URL filtering relied on regex-based allow and deny lists without robust host resolution or IP validation, allowing crafted URLs using hostname resolution, redirects, uppercase schemes, or IPv4-mapped IPv6 notation to access localhost, private networks, or cloud metadata services. This enabled server-side request forgery through download, Chromium fetch, or webhook features, potentially exposing internal services or sensitive metadata.
