Summary
The Alt Text AI – Automatically generate image alt text for SEO and accessibility plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.10.41. 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 post_content of any post or page on the site — including content they do not own — with LLM-generated text influenced by attacker-controlled keywords, enabling black-hat SEO manipulation and unauthorized consumption of the site owner's paid AltText.ai API credits. The nonce required to invoke the action is emitted on every admin page including /wp-admin/profile.php, which is accessible to Subscribers, making the nonce trivially obtainable by any authenticated user.
