Summary
A vulnerability exists in the Elliptic package version 6.5.6 for Node.js that allows for EDDSA signature malleability. This occurs due to a missing signature length check, which can enable zero-valued bytes to be either removed or appended. This oversight may allow attackers to manipulate valid signatures without detection, potentially leading to various security implications in applications that rely on this cryptographic functionality.
