CVE-2025-8401: HT Mega Elementor Information Disclosure

CVE-2025-8401 Overview

CVE-2025-8401 is a sensitive information exposure vulnerability in the HT Mega – Absolute Addons For Elementor plugin for WordPress. The flaw affects all versions up to and including 2.9.1 and resides in the get_post_data function. Authenticated attackers with Author-level access or above can extract the content of private posts, password-protected posts, and draft posts and pages. The vulnerability is classified under CWE-285: Improper Authorization and stems from missing capability checks on a callable data-retrieval routine within the plugin's block system.

Critical Impact
Authenticated users with contributor-adjacent privileges can read unpublished editorial content, embargoed material, and password-protected pages without authorization.

Affected Products

HasThemes HT Mega – Absolute Addons For Elementor (free, WordPress) versions <= 2.9.1
WordPress sites running the plugin with Author-level or higher user accounts
Sites where editorial workflows rely on draft or private post confidentiality

Technical Details for CVE-2025-8401

Vulnerability Analysis

The vulnerability exists in the get_post_data function of the HT Mega plugin, part of the Manage_Styles class within the plugin's block subsystem. The function retrieves post content to render Elementor-driven blocks. It fails to verify whether the requesting user has the WordPress capability required to read the target post's status. As a result, callers can request post identifiers whose visibility is normally restricted to editors, administrators, or the post owner.

WordPress enforces separate capabilities for reading posts based on status: read_private_posts, edit_post, and post-password checks. The plugin bypasses these checks and returns raw post data to any authenticated caller who can invoke the block's data endpoint. Author role and above satisfies the privilege threshold because that role can legitimately load the block editor context that reaches get_post_data.

Root Cause

The root cause is missing authorization enforcement [CWE-285]. The get_post_data handler queries the requested post using its ID and returns content, title, and metadata without invoking current_user_can() against the post's visibility state or password. Draft, private, and password-protected posts are returned identically to public posts.

Attack Vector

An attacker first obtains or compromises an account holding the Author role or higher on the target WordPress site. The attacker then submits a request to the plugin's block-rendering endpoint, supplying the ID of a target private, draft, or password-protected post. The endpoint invokes get_post_data, which returns the confidential post content in the response. No user interaction from the victim is required, and the attack completes over the network in a single request. Refer to the WordPress Plugin Style Management source and the Wordfence Vulnerability Analysis for the affected code location.

Detection Methods for CVE-2025-8401

Indicators of Compromise

Requests from Author-level accounts to HT Mega block AJAX or REST endpoints referencing post IDs the user does not own.
Unexpected access patterns where a single low-privilege user enumerates sequential post IDs through plugin endpoints.
Access log entries containing HT Mega handler names paired with Author, Contributor-elevated, or newly created accounts.

Detection Strategies

Audit WordPress access logs for calls to HT Mega block handlers invoked by users without edit_others_posts capability.
Correlate plugin endpoint requests with the post_status of the requested post ID and flag reads against draft, private, or password-protected posts.
Deploy a WordPress security plugin ruleset that inspects plugin AJAX responses for content belonging to unpublished posts.

Monitoring Recommendations

Enable WordPress user activity logging that records post reads performed by lower-privileged roles.
Monitor for creation of new Author-level accounts followed by immediate plugin endpoint activity.
Track outbound response sizes from HT Mega endpoints; abnormally large payloads to Author accounts warrant review.

How to Mitigate CVE-2025-8401

Immediate Actions Required

Update HT Mega – Absolute Addons For Elementor to a version later than 2.9.1 that includes the fix from WordPress Changeset #3336533.
Review all Author, Editor, and custom-role accounts and remove any that are inactive, unrecognized, or unnecessary.
Rotate passwords on password-protected posts if the site handled sensitive embargoed content.

Patch Information

HasThemes addressed the vulnerability in the plugin repository under WordPress Changeset #3336533. The fix adds authorization checks to the get_post_data function so that requests for private, draft, or password-protected posts respect WordPress capability and password requirements. Site administrators should update through the WordPress plugin dashboard or via WP-CLI.

Workarounds

Restrict Author-level and higher access to trusted users only until the plugin is updated.
Deactivate the HT Mega plugin on sites that cannot immediately update and that host confidential draft content.
Apply web application firewall rules that block plugin block endpoints when the requesting user lacks edit_others_posts.

bash

# Update HT Mega via WP-CLI to the patched release
wp plugin update ht-mega-for-elementor

# Verify the installed version is greater than 2.9.1
wp plugin get ht-mega-for-elementor --field=version

# Audit Author-level and higher accounts
wp user list --role=author --fields=ID,user_login,user_registered,user_email
