CVE-2014-5204: Debian Linux

Medium severity, CVSS 6.8. EPSS: 1.9% chance of exploitation in the next 30 days.

wp-includes/pluggable.php in WordPress before 3.9.2 rejects invalid CSRF nonces with a different timing depending on which characters in the nonce are incorrect, which makes it easier for remote attackers to bypass a CSRF protection mechanism via a brute-force attack.

Affected products

• Debian Debian Linux: version 7.0 only
• WordPress WordPress: up to and including 3.9.1; version 3.9.0 only
