CVE-2026-16235
CWE-338Published: July 20, 2026· Updated: Jul 20, 2026
Official 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.
Risk Analysis
Crypt::Password versions through 0.28 use a predictable random number generator for salt creation, which is cryptographically insecure. Given the critical CVSS score of 9.8, this flaw could allow attackers to compromise password security, though no exploitation data is currently available.
There is no known public exploit for this vulnerability, and it is not listed in CISA's KEV catalog.
Users should update to a version of Crypt::Password that utilizes a cryptographically secure random number generator.
Technical Analysis
CVE-2026-16235 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
