Animated Text Block <= 1.2.6 — Missing Authorization to Unauthenticated Sensitive Information Exposure via 'id' Shortcode Attribute

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under Animated Text Block – Add Typing and Looping Text Effects.
• No admin access? Run a passive check of your site. It reads public files only.
• No account is needed to exploit this. Treat any exposed site on an affected version as at risk.

What to do

1. Update to version 1.2.7, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch Animated Text Block – Add Typing and Looping Text Effects to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Wordfence PRISM.

The Animated Text Block plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 1.2.6 via the 'animated-text' shortcode. This is due to the atb_shortcode_handler() function fetching an arbitrary post by attacker-supplied ID and, in the 'publish' branch, calling displayContent() with no capability check and no validation that the post's post_type is the plugin's own CPT or is otherwise viewable (is_post_type_viewable()). This makes it possible for authenticated attackers, with Contributor-level access and above, to read the rendered block content of any published post, including posts of non-public custom post types (public=false, show_in_rest=false) that WordPress would otherwise hide from direct URLs and the REST API.
