Last modified Jun 16, 2026

CVE-2005-2946 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. The default configuration on OpenSSL before 0.9.8 uses MD5 for creating message digests instead of a more cryptographically strong algorithm, which makes it easier for remote attackers to forge certificates with a valid certificate authority signature.. EPSS estimates a 0.84% chance of exploitation in the next 30 days.
