# aBlocks WordPress plugin: shortcode leaks password-protected post content

Link for people: https://infrastack.ai/live/CVE-2026-118801 (this .md is for agents)

The aBlocks WordPress plugin up to and including 2.18.0 lets a logged-in contributor embed a shortcode with another post's ID to read the full body of that post, even when it is password-protected. An author can publish such a post so unauthenticated visitors see the protected content.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed aBlocks plugin version in the WordPress admin under Plugins; versions up to and including `2.18.0` are affected.
- Review whether password-protected posts exist on the site and whether contributors can edit posts.

## From the sources

The aBlocks – Gutenberg Blocks, User Dashboard Builder, Popup Builder, Form Builder & Animation Builder plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.18.0 via the 'id' parameter. This makes it possible for authenticated attackers, with contributor-level access and above, to extract the full rendered body content of any password-protected post of any post type by embedding the shortcode with the target post's ID. Author-level attackers and above can additionally publish a post embedding the shortcode, exposing the password-protected content to unauthenticated visitors.
