mediumpriority · track · 32EPSS 0.027 · 86 %ileDEEUUSEPSS · scored 2026-10-27
The Elliptic package 6.5.2 for Node.js allows ECDSA signature malleability via variations in encoding, leading '\0' bytes, or integer overflows. This could conceivably have a security-relevant impact if an application relied on a single canonical signature.
