DescriptionCVE.org

The Advanced Form Integration - Connect Forms to 200+ Apps plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.6.0. 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 subscriber-level access and above, to overwrite the site's stored MailUp OAuth tokens in the adfoin_mailup_keys option with attacker-controlled tokens, hijacking future form-submission data to a MailUp account they control or nulling the tokens to break the integration entirely. This is exploitable by any authenticated user who can reach /wp-admin/profile.php, as admin_init fires for all logged-in users visiting any wp-admin page.

AnalysisAI

Authorization bypass in Advanced Form Integration plugin for WordPress up to 2.6.0 allows authenticated attackers with subscriber-level access to overwrite MailUp OAuth tokens. The missing authorization check on admin_init enables token hijacking, letting attackers redirect form-submission data to a controlled MailUp account or break the integration. Exploitation requires only a subscriber account and visiting any wp-admin page, making it a low‑complexity attack with moderate impact on data integrity.
