CRITICAL 9.1REMOTEUPGRADE

CVE-2025-57801 is a critical-severity flaw (CVSS 9.1) affecting gnark. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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 essential constraints, multiple distinct witnesses can satisfy the same public inputs. In protocols where nullifiers or anti-replay checks are derived
