CVE-2026-23966
CriticalSummary
W bibliotece sm-crypto, która implementuje chińskie algorytmy kryptograficzne SM2, SM3 i SM4, występuje podatność na odzyskanie klucza prywatnego w logice deszyfrowania SM2 przed wersją 0.3.14. Atakujący może odzyskać klucz prywatny po wielokrotnym interakcji z interfejsem deszyfrowania SM2.
Risk Assessment
Organizacje korzystające z tej biblioteki mogą być narażone na utratę poufności danych, co może prowadzić do poważnych konsekwencji prawnych i reputacyjnych. Właściwe zabezpieczenie kluczy prywatnych jest kluczowe dla ochrony danych.
Recommendation
Zaleca się aktualizację biblioteki sm-crypto do wersji 0.3.14 lub nowszej, aby usunąć tę podatność. Dodatkowo, warto przeprowadzić audyt bezpieczeństwa istniejących kluczy prywatnych.

Original NVD description (English source)
sm-crypto provides JavaScript implementations of the Chinese cryptographic algorithms SM2, SM3, and SM4. A private key recovery vulnerability exists in the SM2 decryption logic of sm-crypto prior to version 0.3.14. By interacting with the SM2 decryption interface multiple times, an attacker can fully recover the private key within approximately several hundred interactions. Version 0.3.14 patches the issue.
