CVE-2026-32322 soroban-sdk: `Fr` scalar field equality comparison bypasses modular reduction

soroban-sdk is a Rust SDK for Soroban contracts. Prior to 22.0.11, 23.5.3, and 25.3.0, The Fr scalar field types for BN254 and BLS12-381 in soroban-sdk compared values using their raw U256 representation without first reducing modulo the field modulus r. This caused mathematically equal field...

CVE-2026-32322

Summary : The Soroban SDK (Rust) Fr scalar field types for BN254 and BLS12-381 were vulnerable prior to 22.0.11, 23.5.3, and 25.3.0 because equality comparisons used raw U256 values without reducing modulo the field modulus r. This could cause mathematically equal field elements to compare as une...
