What is CVE-2026-52776?

The Compliance-trestle platform suffers from a configuration issue where the URLSecurityValidator fails to prevent server-side request forgery on specific versions. Attackers can exploit this flaw to access restricted network endpoints, including local services and cloud instance metadata, by influencing OSCAL artifacts that are fetched by the platform. The ineffective blocking of certain IP addresses allows unauthorized access to sensitive information. This issue has been addressed in newer versions, ensuring enhanced security for users.
