Server-Side Request Forgery in Huly Platform Print Service

Publication date: 2026-09-14

Last updated on: 2026-09-14

Assigner: VulnCheck

Description
Huly Platform through 0.7.426 contains a server-side request forgery vulnerability in the print service due to missing hostname allowlist validation. Authenticated workspace members can supply arbitrary URLs to the print endpoint, which Puppeteer renders and returns as downloadable PDFs or images, enabling access to internal metadata services and network hosts.

Executive Summary

Huly Platform through version 0.7.426 has a server-side request forgery (SSRF) vulnerability in its print service. This flaw allows authenticated workspace members to send arbitrary URLs to the print endpoint. Puppeteer then renders these URLs and returns them as downloadable PDFs or images. The vulnerability exists because the system does not validate hostnames against an allowlist, enabling access to internal metadata services and other network hosts.

Detection Guidance

Detecting this SSRF vulnerability requires checking if the Huly Platform's print service is exposed and if arbitrary URLs can be supplied to it. Inspect network traffic for outbound requests from the Huly Platform to internal hosts or metadata services. Check server logs for unusual PDF/image generation requests with external or internal URLs.

Impact Analysis

An attacker with authenticated access could exploit this to access internal network services or metadata, potentially leading to unauthorized data exposure or further network compromise. The impact includes potential data leaks, unauthorized access to sensitive services, and increased risk of lateral movement within the network.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection principles and HIPAA's security requirements. Non-compliance may result in legal penalties, reputational damage, and loss of trust due to potential data breaches.

Mitigation Strategies

Upgrade Huly Platform to a version beyond 0.7.426 where the hostname allowlist validation is implemented. If immediate upgrade is not possible, restrict network access to the print service endpoint and block outbound requests to internal or sensitive hosts. Review and filter all URL inputs to the print endpoint to ensure only allowed domains are processed.
