rs-soroban-sdk: `Fr` scalar field equality comparison bypasses modular reduction

Security Advisory: Incorrect Equality for Fr Scalar Field Types BN254, BLS12-381 Summary Missing modular reduction in Fr causes incorrect equality comparisons for BN254 and BLS12-381 types in soroban-sdk. Impact The Fr scalar field types for BN254 and BLS12-381 in soroban-sdk compared values usin...

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...
