========================================================================
CVE ID: CVE-2026-16235
Distribution: Crypt-Password
Versions: through 0.28
MetaCPAN: https://metacpan.org/dist/Crypt-Password
Crypt::Password versions through 0.28 for Perl generate insecure random
values for salts
Description
-----------
Crypt::Password versions through 0.28 for Perl generate insecure random
values for salts.
These versions use the built-in rand function, which is predictable and
unsuitable for cryptography.
Problem types
-------------
- CWE-338 Use of Cryptographically Weak Pseudo-Random Number Generator
(PRNG)
Workarounds
-----------
Users can generate a salt manually using a module such as
Crypt::URandom::Token, and pass the salt directly to the password and
crypt_password methods.
This module has not been updated since 2012.
Users should migrate to an alternative solution.
