Publication date: 2026-10-07

Last updated on: 2026-10-07

Assigner: VulnCheck

Description
Gophish 0.11.0 through 0.12.1 contains a server-side request forgery vulnerability that allows authenticated low-privileged users to reach loopback and private hosts via POST /api/import/site. Attackers can submit internal URLs, which the default dialer deny list does not block, to read service responses and enumerate internal hosts and ports through error messages.

Executive Summary

This is a Server-Side Request Forgery (SSRF) vulnerability in Gophish versions 0.11.0 through 0.12.1. It allows authenticated low-privileged users to submit internal URLs via the POST /api/import/site endpoint. The default dialer's deny list fails to block these requests, enabling attackers to read service responses and enumerate internal hosts and ports through error messages.

Detection Guidance

Monitor Gophish logs for POST requests to /api/import/site with internal or loopback URLs. Check for error messages indicating failed connections to private hosts. Use network monitoring tools to inspect outbound connections from the Gophish server to unauthorized destinations.

Impact Analysis

An attacker could exploit this to access internal services, read sensitive data from internal hosts, or map your internal network infrastructure. This could lead to further attacks like data exfiltration or lateral movement within your network.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection principles or HIPAA's security requirements for protected health information. Organizations may face compliance violations and potential fines if exploited.

Mitigation Strategies

Upgrade Gophish to a patched version if available. Restrict access to the /api/import/site endpoint to trusted users only. Review and update the dialer's deny list to explicitly block loopback and private IP ranges. Implement network-level restrictions to prevent outbound connections to unauthorized hosts.
