    CVE-2026-44368 (GCVE-0-2026-44368)

    Vulnerability from nvd – Published: 2026-05-13 20:18 – Updated: 2026-05-15 18:44

    Title
    PyQuorum: Timing side‑channel in mul_mod
    Summary
    PyQuorum is a cryptographic library for secret sharing and key management. Prior to 0.2.1, the mul_mod function implements multiplication via a binary expansion loop whose execution time depends on the Hamming weight of the second operand (the exponent). An attacker who can measure the time of secret‑sharing operations (e.g., via a remote service) could progressively recover the values of shares, ultimately leading to secret reconstruction. This vulnerability is fixed in 0.2.1.
