CVE-2026-87744 Red Hat CVE debrief

Who should care

Defenders and developers using Quarkus REST Data Panache should assess exposure and verify configurations to prevent unauthorized access. This includes reviewing customized operations and security annotations, implementing additional security controls, and prioritizing verification and remediation efforts. Security teams and vulnerability management teams should also be aware of the potential impacts and take necessary actions to secure Quarkus deployments

Why it matters

This vulnerability allows unauthenticated attackers to bypass security controls on generated endpoints in Quarkus REST Data Panache, potentially leading to unauthorized information disclosure or data modification. Defenders and developers should verify configurations and update security annotations to prevent unauthorized access.

• Potential unauthorized information disclosure
• Potential data modification by unauthorized users
• Need for verification of customized operations and security annotations
• Priority for updating and securing Quarkus applications

Technical summary

The vulnerability occurs when developers customize specific operations using @MethodProperties without explicitly re-declaring security roles, causing the code generator to silently drop class-level security requirements. This results in affected endpoints defaulting to permissive, unauthenticated access, potentially leading to unauthorized information disclosure or data modification. The issue arises from the interaction between Quarkus REST Data Panache's security features and custom operation configurations. Affected deployments should review and update security annotations to prevent unauthorized access.

Defensive priority

Defenders should prioritize verifying and remediating this vulnerability in Quarkus applications using REST Data Panache, especially where unauthenticated access could lead to significant impact.

Recommended defensive actions

• Verify Quarkus applications using REST Data Panache for vulnerable configurations
• Review and update security annotations for customized operations
• Implement additional security controls to prevent unauthorized access
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
