CVE-2025-10915: Dreamer Blog WordPress Auth Bypass Flaw

CVE-2025-10915 Overview

CVE-2025-10915 is a critical authorization bypass vulnerability affecting The Dreamer Blog WordPress theme through version 1.2. The vulnerability stems from a missing capability check that allows unauthenticated attackers to perform arbitrary installations on affected WordPress sites. This flaw enables remote attackers to install malicious plugins or themes without proper authorization, potentially leading to complete site compromise.

Critical Impact

Unauthenticated attackers can exploit this vulnerability to install arbitrary plugins or themes on vulnerable WordPress sites, enabling remote code execution, data theft, and complete site takeover.

Technical Details for CVE-2025-10915

Vulnerability Analysis

This vulnerability represents a critical authorization bypass flaw in The Dreamer Blog WordPress theme. The core issue is a missing capability check in the theme's installation functionality, which should verify that users attempting to install components have the appropriate administrative privileges. Without this security control, the theme exposes dangerous installation functions to any user, including unauthenticated visitors.

The attack can be executed remotely over the network without requiring any prior authentication or user interaction. An attacker exploiting this vulnerability gains the ability to compromise the confidentiality, integrity, and availability of the affected WordPress installation. The arbitrary installation capability can be leveraged to deploy backdoored plugins, web shells, or malicious themes that provide persistent access to the compromised site.

Root Cause

The root cause of CVE-2025-10915 is improper access control implementation within The Dreamer Blog WordPress theme. WordPress provides built-in capability checking functions such as current_user_can() that developers should use to verify user permissions before executing privileged operations. The vulnerable theme fails to implement these checks before allowing installation operations, leaving the functionality exposed to unauthorized users.

This represents a broken access control vulnerability where the application does not properly enforce authorization requirements for sensitive administrative functions. The theme likely registers an AJAX handler or REST API endpoint for installation operations but neglects to verify the requesting user's capabilities before processing the request.

Attack Vector

The attack vector for this vulnerability is network-based, requiring no authentication, no user interaction, and low attack complexity. An attacker can target any WordPress site running the vulnerable Dreamer Blog theme by sending crafted HTTP requests to the exposed installation endpoint.

The typical exploitation flow involves:

1. Identifying a WordPress site using The Dreamer Blog theme version 1.2 or earlier
2. Sending a crafted request to the unprotected installation endpoint
3. Specifying a malicious plugin or theme package for installation
4. Gaining code execution through the installed malicious component

Since no authentication is required, attackers can automate scanning and exploitation across large numbers of WordPress sites. For detailed technical information about the vulnerability, see the WPScan Vulnerability Report.

Detection Methods for CVE-2025-10915

Indicators of Compromise

• Unexpected plugins or themes installed on WordPress sites without administrator action
• Unfamiliar AJAX or REST API requests targeting installation endpoints in web server logs
• New administrator accounts created without authorization
• Web shell files or backdoor scripts appearing in the WordPress installation directory
• Suspicious outbound network connections from the web server

Detection Strategies

• Monitor WordPress admin-ajax.php and REST API endpoints for unusual installation-related requests from unauthenticated sources
• Implement file integrity monitoring to detect unauthorized changes to the wp-content/plugins/ and wp-content/themes/ directories
• Review web server access logs for POST requests containing installation parameters from non-authenticated sessions
• Deploy web application firewall rules to detect and block unauthorized installation attempts

Monitoring Recommendations

• Enable WordPress audit logging to track all plugin and theme installation events with user attribution
• Configure alerting for any installation activity occurring outside of maintenance windows or from unexpected IP addresses
• Implement real-time file system monitoring on WordPress content directories
• Review server-side execution logs for new or modified PHP files in theme and plugin directories

How to Mitigate CVE-2025-10915

Immediate Actions Required

• Deactivate and remove The Dreamer Blog WordPress theme immediately if running version 1.2 or earlier
• Audit all installed plugins and themes for any unauthorized additions and remove suspicious components
• Check for newly created administrator accounts and remove any that are unauthorized
• Scan the WordPress installation for web shells, backdoors, or other malicious files
• Review server access logs for evidence of exploitation attempts

Patch Information

As of the last NVD update on 2026-01-13, users should check the WPScan Vulnerability Report for the latest patch information and remediation guidance from the theme developer. Users are advised to update to a patched version when available or switch to an alternative WordPress theme that receives regular security updates.

Workarounds

• Switch to an alternative, actively maintained WordPress theme until a security patch is available
• Implement web application firewall rules to block requests to the vulnerable installation endpoints
• Restrict access to WordPress administrative functions at the network level using IP allowlisting
• Enable WordPress security plugins that provide capability checking and request filtering for theme functions

# WordPress configuration hardening example
# Add to wp-config.php to restrict plugin/theme installation
define('DISALLOW_FILE_MODS', true);

# Alternatively, restrict plugin/theme editing only
define('DISALLOW_FILE_EDIT', true);
