Flamingo <= 2.6.2 - Authenticated (Contributor+) Missing Authorization to Unauthorized Tag Information Disclosure via wp.getTerms and ajax-tag-search
The Flamingo plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.6.2. This is due to the plugin 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 plugin's flamingo_map_meta_cap() filter restricts access to Flamingo's admin UI but does not extend to WordPress core APIs such as XML-RPC wp.getTerms and admin-ajax ajax-tag-search.
