Flamingo < 2.6.3 - Contributor+ Tag Information Disclosure via wp.getTerms and ajax-tag-search

Description

The plugin is vulnerable to authorization bypass, due to not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to enumerate taxonomy terms including channel names derived from Contact Form 7 form titles that may reveal internal form purposes, department names, or workflow identifiers, as well as submission counts per channel and contact tag names. The flamingo_map_meta_cap() filter restricts access to the plugin's admin UI but does not extend to WordPress core APIs such as XML-RPC wp.getTerms and admin-ajax ajax-tag-search.
