Vulnerability from fkie_nvd - Published: 2025-12-31 06:15 - Updated: 2026-06-17 10:00
Severity
4.5 (Medium) - CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N
Summary
libsodium before ad3004e, in atypical use cases involving certain custom cryptography or untrusted data to crypto_core_ed25519_is_valid_point, mishandles checks for whether an elliptic curve point is valid because it sometimes allows points that aren't in the main cryptographic group.
