Last modified

CVE-2020-13822 is a high-severity vulnerability rated 7.7/10 on the CVSS scale. 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.. EPSS estimates a 2.63% chance of exploitation in the next 30 days.
