The blinding configure option is only for the base C implementation of Curve25519. It is not needed, or available with; ARM assembly builds, Intel assembly builds, and the small Curve25519 feature. While the side-channel attack on extracting a private key would be very difficult to execute in practice, enabling blinding provides an additional layer of protection for devices that may be more susceptible to physical access or side-channel observation.","published":"2025-07-18T23:15:24.000Z","lastModified":"2026-06-17T10:04:52.000Z","status":"Analyzed","sourceIdentifier":"facts@wolfssl.com","cvss":{"version":"4.0","score":5.6,"severity":"MEDIUM","vector":"CVSS:4.0/AV:P/AC:H/AT:P/PR:L/UI:A/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-385"],"affected":["wolfssl/wolfssl"],"epss":{"score":0.00218,"percentile":0.122,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.22%).
