CVE-2020-11735 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. The private-key operations in ecc.c in wolfSSL before 4.4.0 do not use a constant-time modular inverse when mapping to affine coordinates, aka a "projective coordinates leak.". EPSS estimates a 1.29% chance of exploitation in the next 30 days.
