Server-Side Request Forgery in Red Hat Quay

Publication date: 2026-08-14

Last updated on: 2026-08-14

Assigner: Red Hat, Inc.

Description

A flaw was found in Red Hat Quay. A user with FEATURE_BUILD_SUPPORT enabled and repository write access can exploit a Server-Side Request Forgery (SSRF) vulnerability within the build API. This allows the user to provide a malicious URL, causing the Quay builder to make requests to internal network addresses. Such an action could lead to the disclosure of sensitive internal information.

Attack-Flow Graph

Executive Summary

This is a Server-Side Request Forgery (SSRF) vulnerability in Red Hat Quay. A user with FEATURE_BUILD_SUPPORT enabled and repository write access can provide a malicious URL to the build API. This causes the Quay builder to make requests to internal network addresses, potentially exposing sensitive internal information.

Detection Guidance

To detect this SSRF vulnerability in Red Hat Quay, monitor network traffic from the Quay builder component for unexpected outbound requests to internal network addresses. Check logs for build API calls with suspicious URLs pointing to private IP ranges (e.g., 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16). Enable detailed logging in Quay and inspect for FEATURE_BUILD_SUPPORT enabled users making build requests.

Impact Analysis

An attacker could exploit this to access internal systems or data, leading to unauthorized information disclosure. This may result in data breaches, loss of confidential data, or further network compromise depending on the internal network's security.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating compliance requirements such as GDPR (data protection) or HIPAA (health information privacy). Organizations may face legal penalties, reputational damage, and loss of trust due to non-compliance.

Mitigation Strategies

Disable the FEATURE_BUILD_SUPPORT setting in Red Hat Quay if not required. Restrict repository write access to trusted users only. Monitor network traffic for unusual requests originating from the Quay builder component.
