CVE-2014-3694
Status: ModifiedMedium (6.4)—
The (1) bundled GnuTLS SSL/TLS plugin and the (2) bundled OpenSSL SSL/TLS plugin in libpurple in Pidgin before 2.10.10 do not properly consider the Basic Constraints extension during verification of X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
CVSS
- Version: 2.0
- Vector: AV:N/AC:L/Au:N/C:P/I:P/A:N
- Base score: 6.4
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 2.35%
- Percentile among all scored CVEs: 83
- Score date: 10/11/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
