CVE-2025-69277 is a medium-severity vulnerability rated 4.5/10 on the CVSS scale. 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.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
