CVE-2026-9638
HighCVSS 7.5Exploitation Probability (EPSS)
Low risk9th percentile - higher than 9% of all known CVEs
Summary
Crypt::PBKDF2 versions before 0.261630 for Perl generate insecure random values for salts. They use the built-in rand function, which is predictable and unsuitable for cryptography.
Risk Assessment
The use of predictable salts can lead to easier password cracking, posing a serious threat to user data security.
Recommendation
It is recommended to upgrade to version 0.261630 or later to ensure secure salt generation.
Other vulnerabilities in Crypt::PBKDF2
See all- CVE-2017-20240Medium
Crypt::PBKDF2 versions before 0.261630 for Perl are vulnerable to timing attacks. The use of Perl's built-in eq comparison may allow an attacker to guess the underlying derived key by analyzing timing discrepancies.
- CVE-2026-9641Medium
Crypt::PBKDF2 versions before 0.261630 for Perl have a weak default algorithm and number of iterations. The default algorithm is HMAC-SHA1, which should only be used for legacy systems.
