CVE-2026-47372
Crypt::SaltedHash Perl modules up to version 0.09 generate salts using the built‑in rand function, which is predictable and not suitable for cryptographic use. This flaw means that the salts used in password hashing can be guessed, weakening the security of stored passwords.
No official fix yet. If none appears within 45 days of first tracking, this entry is removed automatically.
Who is affected
Perl developers using the Crypt::SaltedHash module, specifically versions 0.09 and earlier.
Real-world impact
An attacker who can predict the salts can precompute hash tables or perform targeted brute‑force attacks against stored passwords, potentially gaining unauthorized access to user accounts.
Why this severity
The CVSS score of 9.1 reflects a network‑accessible vulnerability that requires no special privileges or user interaction, has low complexity, and fully compromises confidentiality and integrity of stored credentials.
What to do about it
No official fix or mitigation is documented in the sources yet. Monitor the vendor advisory and apply the patch as soon as it is released.
