CVE-2019-10764

CVE-2019-10764 describes a timing attack vulnerability in simplito elliptic-php versions prior to 1.0.6. This flaw could allow an attacker to practically recover the long-term private key under specific conditions by exploiting leakage of the scalar's bit-length during elliptic curve scalar multiplication. With a CVSS score of 7.4 (High), this vulnerability is network-exploitable with high attack complexity, potentially leading to high confidentiality and integrity impacts. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
