Until an official fix is available, restrict editor-level permissions carefully and consider disabling the Meta-box GalleryMeta plugin in multi-site environments or where unfiltered_html is disabled. Monitor for updates from the plugin vendor regarding patches or official mitigations.
Description
The Meta-box GalleryMeta plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 3.0.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with editor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
