CVE-2026-6966

Improper verification of cryptographic signature uniqueness in delegated role validation in awslabs/tough before tough-v0.22.0 allows remote authenticated users to bypass the TUF signature threshold requirement by duplicating a valid signature, causing the client to accept forged delegated role...

CVE-2026-33895

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...

GHSA-434G-2637-QMQR Elliptic's verify function omits uniqueness validation

The Elliptic package 6.5.5 for Node.js for EDDSA implementation does not perform the required check if the signature proofs is within the bounds of the order n of the base point of the elliptic curve, leading to signature malleability. Namely, the verify function in lib/elliptic/eddsa/index.js...
