CVE-2026-87744
CRITICAL 9.1A flaw was found in Quarkus REST Data Panache. This vulnerability allows unauthenticated attackers to bypass security controls on generated endpoints. When a developer customizes a specific operation using @MethodProperties without explicitly re-declaring security roles, the code generator silently drops class-level security requirements. This results in the affected endpoint defaulting to permissive, unauthenticated access, potentially leading to unauthorized information disclosure or data modification.
Severe if exploited (CVSS 9.1), but no known exploitation and low modeled probability. Patch on a normal cadence.
