CVE-2025-53997: Houzez Theme Authorization Bypass Flaw

CVE-2025-53997 Overview

CVE-2025-53997 is a missing authorization vulnerability in the favethemes Houzez WordPress theme. The flaw affects all versions up to and including 4.0.4. It stems from incorrectly configured access control security levels, allowing authenticated users with low privileges to access functionality they should not reach. The weakness maps to CWE-862: Missing Authorization. Houzez is a real estate theme widely deployed on WordPress sites, which increases its exposure footprint across property listing portals.

Critical Impact
Authenticated attackers with minimal privileges can exploit broken access control to perform unauthorized actions affecting data integrity within Houzez-powered WordPress sites.

Affected Products

favethemes Houzez WordPress theme versions through 4.0.4
WordPress installations using Houzez as the active theme
Real estate listing sites built on the Houzez theme framework

Technical Details for CVE-2025-53997

Vulnerability Analysis

The vulnerability is a broken access control issue in the Houzez theme. The theme exposes functionality that fails to verify whether the requesting user has the required authorization before executing an action. An attacker only needs a low-privilege authenticated session on the target WordPress site to reach the vulnerable code path. The flaw affects integrity but does not directly expose confidential data or disrupt availability, consistent with the Exploit Prediction Scoring System (EPSS) placing this issue in the lower likelihood tier for near-term exploitation.

Root Cause

The root cause is a missing capability check [CWE-862]. The Houzez theme defines handlers that should be restricted to specific user roles or ownership contexts. The code path does not enforce current_user_can() validation or an equivalent authorization check before processing the request. This design error allows any authenticated user to invoke restricted operations regardless of their intended privilege level.

Attack Vector

Exploitation requires network access to the WordPress site and a valid authenticated session with low privileges, such as a subscriber account. On sites where user registration is open, this prerequisite is trivial to satisfy. The attacker issues a crafted HTTP request to the vulnerable Houzez endpoint. Because the handler omits the authorization check, the server processes the request and performs the privileged action. User interaction is not required. See the Patchstack Houzez Theme Vulnerability advisory for additional technical context.

Detection Methods for CVE-2025-53997

Indicators of Compromise

Unexpected modifications to property listings, agent profiles, or theme-managed records authored by low-privilege accounts
HTTP POST requests from subscriber-level accounts targeting Houzez AJAX actions or theme endpoints
Newly registered WordPress accounts followed shortly by requests to Houzez-specific action handlers

Detection Strategies

Review WordPress access logs for authenticated requests to Houzez endpoints originating from accounts that lack an editorial or administrative role
Correlate admin-ajax.php or REST API traffic with the acting user role recorded in WordPress session data
Audit database change history for records modified by accounts without the expected capabilities

Monitoring Recommendations

Enable verbose logging on WordPress with a security plugin that records user role, action name, and parameters for AJAX and REST calls
Alert on repeated 200-response requests to Houzez action handlers from the same low-privilege user within short time windows
Monitor for creation of new subscriber accounts followed by writes to theme-managed content tables

How to Mitigate CVE-2025-53997

Immediate Actions Required

Upgrade the Houzez theme to a version released after 4.0.4 that addresses the broken access control issue
Disable open user registration on affected sites until the patched version is deployed
Audit existing subscriber-level accounts and remove any that are unknown or inactive

Patch Information

The vendor advisory from Patchstack confirms the vulnerability affects Houzez versions up to and including 4.0.4. Site administrators should consult the Patchstack Houzez Theme Vulnerability advisory and the favethemes update channel for the fixed release. Apply the update through the WordPress theme updater or by replacing the theme files with the patched version.

Workarounds

Restrict access to vulnerable Houzez endpoints at the web application firewall layer by blocking requests from accounts without the editor or administrator role
Temporarily set users_can_register to false in WordPress general settings to prevent new low-privilege account creation
Apply least-privilege role assignments and remove unused subscriber accounts to reduce the pool of accounts capable of exploitation

bash

# WP-CLI commands to reduce exposure until the patch is applied
wp option update users_can_register 0
wp user list --role=subscriber --format=table
wp theme update houzez
