CVE-2025-15444: Iamb crypt\ improper verification of cryptographic signature vulnerability

Iamb · Crypt\

Crypt::Sodium::XS module versions prior to 0.000042, for Perl, include a vulnerable version of libsodium libsodium <= 1.0.20 or a version of libsodium released before December 30, 2025 contains a vulnerability documented as CVE-2025-69277  https://www.cve.org/CVERecord?id=CVE-2025-69277 . The libsodium vulnerability states: 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. 0.000042 includes a version of libsodium updated to 1.0.20-stable, released January 3, 2026, which includes a fix for the vulnerability.
