CVE-2026-16235

Summary

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.

Affected Software

Weaknesses

• CWE-338: 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.
