Upgrade github.com/gotenberg/gotenberg/v8/pkg/gotenberg to version 8.33.0 or higher.
Overview
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) in the IsPublicIP function. An attacker can access internal network resources and potentially exfiltrate sensitive information by crafting a DNS AAAA record that resolves to specific IPv6 prefixes, which are incorrectly classified as public IPs. This allows outbound HTTP requests to be tunneled to internal services such as cloud metadata endpoints, leading to possible credential leakage. This is only exploitable if the deployment is configured with WithDenyPrivateIPs(true) on dual-stack or NAT64-enabled hosts.
