Technical details
The vulnerability exists in the WPDA_Apps.php REST API handler, where the 'rel_tab' parameter is not properly validated, allowing unauthenticated attackers to access database contents. An attacker can craft malicious requests to extract rows and columns from any database table backing a published app when REST API authorization is set to 'anonymous' (the default configuration). This requires only that an administrator has published at least one app with anonymous REST API access enabled.
