CVE-2026-8463 Crypt::Argon2 versions from 0.017 before 0.031 for Perl perform a heap out-of-bounds read in argon2_verify on empty encoded input

Crypt::Argon2 versions from 0.017 before 0.031 for Perl perform a heap out-of-bounds read in argon2verify on empty encoded input. The auto-detect form of argon2verify passes encodedlen - 1 as the length argument to memchr without checking that encodedlen is non-zero. When the encoded string is...

CVE-2026-8463

Crypt::Argon2 for Perl (versions 0.017 before 0.031) contains a heap out-of-bounds read in argon2_verify when given an empty encoded input. The auto-detect path passes encoded_len-1 to memchr without ensuring encoded_len is non-zero; with an empty string this underflows to SIZE_MAX and may cause ...
