Vulnerability Details CVE-2026-5088
Apache::API::Password versions through 0.5.2 for Perl can generate insecure random values for salts.
The _make_salt and _make_salt_bcrypt methods will attept to load Crypt::URandom and then Bytes::Random::Secure to generate random bytes for the salt. If those modules are unavailable, it will simply return 16 bytes generated with Perl's built-in rand function.
The rand function is unsuitable for cryptographic use.
These salts are used for password hashing.
