gnark is vulnerable to signature malleability in EdDSA and ECDSA due to missing scalar checks

In version before, sig.s used without asserting 0 ≤ S order in Verify function in eddsa.go and ecdsa.go, which will lead to signature malleability vulnerability. Impact Since gnark’s native EdDSA and ECDSA circuits lack essential constraints, multiple distinct witnesses can satisfy the same publi...

Impact Since gnark’s native EdDSA and ECDSA circuits lack essential constraints, multiple distinct witnesses can satisfy the same publi...

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...

CVE-2025-57801 gnark is vulnerable to signature malleability in EdDSA and ECDSA due to missing scalar checks

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...
