Timing Attack Vulnerability in Perl's Crypt::SaltedHash by RRWO
CVE-2026-47373
Currently unrated
What is CVE-2026-47373?
Crypt::SaltedHash, specifically versions up to 0.09, is vulnerable to timing attacks due to the use of Perl's native eq comparison for checking hashes. An attacker may exploit this vulnerability by measuring the time taken for equalities, allowing them to deduce the underlying hash values. This exposure makes it easier to guess sensitive data, thus compromising the security of applications utilizing this cryptographic library. It's recommended to upgrade to the latest version or implement alternative measures to mitigate exposure.
