Last modified Jun 17, 2026

CVE-2019-10764 is a high-severity vulnerability rated 7.4/10 on the CVSS scale. In elliptic-php versions priot to 1.0.6, Timing attacks might be possible which can result in practical recovery of the long-term private key generated by the library under certain conditions. Leakage of a bit-length of the scalar during scalar multiplication is possible on an elliptic curve which might allow practical recovery of the long-term private key.. EPSS estimates a 1.09% chance of exploitation in the next 30 days.
