GHSA-X3FF-W252-2G7J StableLib Ed25519 Signature Malleability via Missing S < L Check

Ed25519 Signature Malleability via Missing S = L to prevent signature malleability. When S = L, SB = S mod LB = S - LB, meaning two different 32-byte S values produce the same verification result. An attacker who observes a valid signature R, S can produce a second valid signature R, S + L for th...

CVE-2026-33895 Forge has signature forgery in Ed25519 due to missing S > L check

Forge also called node-forge is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.4.0, Ed25519 signature verification accepts forged non-canonical signatures where the scalar S is not reduced modulo the group order S = L. A valid signature and its S + L variant...
