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

Vulnerability from cvelistv5 – 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.

Severity

6.9 (Medium)

GHSA-7R92-3JGR-R65Q

Vulnerability from github – Published: 2026-05-06 22:40 – Updated: 2026-05-14 20:42

Summary

pyquorum: Timing side‑channel in mul_mod

Details

Impact

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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
