CVE-2012-3383: WordPress

Low severity, CVSS 2.6. EPSS: 3.1% chance of exploitation in the next 30 days.

The map_meta_cap function in wp-includes/capabilities.php in WordPress 3.4.x before 3.4.2, when the multisite feature is enabled, does not properly assign the unfiltered_html capability, which allows remote authenticated users to bypass intended access restrictions and conduct cross-site scripting (XSS) attacks by leveraging the Administrator or Editor role and composing crafted text.

Affected products
