CVE-2025-57801

gnark is a zero-knowledge proof system framework. In versions prior to 0.14.0, the Verify function in eddsa.go and ecdsa.go used the S value from a signature without asserting that 0 ≤ S order, leading to a signature malleability vulnerability. Because gnark’s native EdDSA and ECDSA circuits lack...

Improper Verification of Cryptographic Signature

Overview Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to missing scalar checks in the Verify and prepareVerification functions. An attacker can produce multiple valid signatures for the same message by manipulating the S value in EdDSA a...
