CVE-2025-65951

Inside Track / Entropy Derby is a research-grade horse-racing betting engine. Prior to commit 2d38d2f, the VDF-based timelock encryption system fails to enforce sequential delay against the betting operator. Bettors pre-compute the entire Wesolowski VDF and include vdfOutputHex in their encrypted bet ticket, allowing the house to decrypt immediately using fast proof verification instead of expensive VDF evaluation. This issue has been patched via commit 2d38d2f.

Summary		(es) Inside Track / Entropy Derby es un motor de apuestas de carreras de caballos de grado de investigación. Versiones anteriores al commit 2d38d2f, el sistema de cifrado con bloqueo de tiempo basado en VDF no logra imponer un retraso secuencial contra el operador de apuestas. Los apostadores precalculan el VDF de Wesolowski completo e incluyen vdfOutputHex en su boleto de apuesta cifrado, permitiendo a la casa de apuestas descifrar inmediatamente utilizando una verificación de prueba rápida en lugar de una costosa evaluación de VDF. Este problema ha sido parcheado a través del commit 2d38d2f.
