AI-Generated

The Flamingo plugin for WordPress is vulnerable to authorization bypass, allowing authenticated attackers with contributor-level access and above to enumerate sensitive taxonomy terms, potentially exposing internal form purposes and workflow identifiers. This vulnerability arises from inadequate verification of user permissions, particularly affecting API endpoints like XML-RPC and admin-ajax. WordPress site administrators using the Flamingo plugin should prioritize this issue to mitigate the risk of information disclosure.

Original NVD Description

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.
