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.

Security readout for executives and security teams

This issue affects old WordPress 3.4.x multisite installations before 3.4.2. A trusted logged-in user with Administrator or Editor privileges could bypass intended HTML restrictions and create cross-site scripting content. It is not a public internet unauthenticated takeover, but it matters where privileged site users are numerous or less trusted. Exposure is limited to WordPress 3.4.x before 3.4.2 with multisite enabled, especially sites allowing Administrator or Editor users who are not fully trusted. Single-site WordPress or patched versions are not identified as affected in the supplied sources. Prioritize as a legacy platform remediation issue. If any WordPress multisite instance still runs 3.4.x before 3.4.2, patch promptly and review privileged users. If no such legacy multisite exists, no action is indicated by the supplied sources. Mitigation focus: Upgrade affected WordPress 3.4.x multisite installations to WordPress 3.4.2 or later.; Follow WordPress 3.4.2 release guidance for the exact supported upgrade path.; Review Administrator and Editor accounts on affected multisite networks..
