CVE-2025-48133: Uncanny Automator Auth Bypass Vulnerability

CVE-2025-48133 Overview

A critical Missing Authorization vulnerability has been identified in the Uncanny Automator plugin for WordPress, developed by Uncanny Owl. This vulnerability enables attackers to exploit incorrectly configured access control security levels, potentially allowing unauthorized access to sensitive plugin functionality and data. The flaw stems from inadequate authorization checks (CWE-862), which can be leveraged remotely without requiring any authentication or user interaction.

Critical Impact

This vulnerability allows unauthenticated attackers to bypass access controls and potentially compromise WordPress sites using the Uncanny Automator plugin, affecting confidentiality, integrity, and availability of the system.

Affected Products

• Uncanny Automator plugin for WordPress from version n/a through 6.4.0.2
• WordPress installations with Uncanny Automator (uncannyowl:uncanny_automator)
• Sites utilizing Uncanny Automator's automation workflow features

Technical Details for CVE-2025-48133

Vulnerability Analysis

This vulnerability is classified as a Missing Authorization flaw (CWE-862), which occurs when the application fails to perform proper authorization checks before granting access to protected resources or functionality. In the context of Uncanny Automator, the plugin does not adequately verify whether a user has the appropriate permissions to perform certain actions, allowing attackers to access functionality that should be restricted to authenticated administrators or privileged users.

The vulnerability is particularly dangerous as it can be exploited remotely over the network without requiring any prior authentication or privileges. The attack complexity is low, meaning that exploitation does not require specialized conditions or significant effort. Successful exploitation can lead to complete compromise of data confidentiality, integrity, and system availability.

Root Cause

The root cause of CVE-2025-48133 lies in the absence of proper authorization checks within the Uncanny Automator plugin's access control implementation. The plugin fails to validate user permissions before processing requests to sensitive endpoints or functions, creating an exploitable gap in the security model. This is a fundamental design flaw where the application assumes trusted input or relies on security through obscurity rather than enforcing explicit authorization at each sensitive operation.

Attack Vector

The attack vector for this vulnerability is network-based, meaning an attacker can exploit it remotely over the internet. The exploitation path involves sending specially crafted requests to the vulnerable WordPress installation running Uncanny Automator. Since no authentication is required, any remote attacker who can reach the WordPress site can attempt exploitation.

The attack does not require user interaction, making it suitable for automated exploitation at scale. Attackers can target WordPress sites running vulnerable versions of Uncanny Automator to gain unauthorized access to automation workflows, potentially manipulating site functionality, exfiltrating sensitive data, or causing service disruption.

Detection Methods for CVE-2025-48133

Indicators of Compromise

• Unexpected or unauthorized automation workflow executions logged in the Uncanny Automator activity logs
• Unusual API requests to Uncanny Automator endpoints from unknown or external IP addresses
• Suspicious access patterns to WordPress admin functions without corresponding authentication events
• Modifications to automation rules or triggers without administrator activity

Detection Strategies

• Monitor WordPress access logs for requests to Uncanny Automator plugin endpoints from unauthenticated sessions
• Implement Web Application Firewall (WAF) rules to detect and block unauthorized access attempts to the plugin
• Review Uncanny Automator audit logs for unauthorized configuration changes or workflow modifications
• Deploy endpoint detection solutions to identify anomalous behavior on WordPress servers

Monitoring Recommendations

• Enable detailed logging for all Uncanny Automator plugin activities and integrate with centralized SIEM solutions
• Configure alerts for failed or suspicious authentication attempts targeting WordPress admin areas
• Regularly audit installed plugin versions and compare against known vulnerable versions
• Implement real-time monitoring of WordPress database changes related to plugin configuration

How to Mitigate CVE-2025-48133

Immediate Actions Required

• Update Uncanny Automator to a version later than 6.4.0.2 immediately to remediate the vulnerability
• Review Uncanny Automator audit logs for any signs of unauthorized access or suspicious activity
• Temporarily disable the Uncanny Automator plugin if an update cannot be applied immediately
• Restrict access to the WordPress admin area and plugin endpoints via IP allowlisting if possible

Patch Information

The vulnerability affects Uncanny Automator versions through 6.4.0.2. Users should update to the latest available version that contains the security fix. Detailed patch information is available through the Patchstack WordPress Vulnerability Database. Site administrators should verify their current plugin version via the WordPress admin dashboard and apply updates through the standard WordPress plugin update mechanism.

Workarounds

• Implement a Web Application Firewall (WAF) with rules specifically targeting unauthorized access to Uncanny Automator endpoints
• Restrict access to the WordPress site at the network level using firewall rules or VPN requirements until patching is complete
• Disable the Uncanny Automator plugin temporarily if it is not business-critical until the patch can be applied
• Monitor for and block suspicious requests targeting WordPress plugin directories via server-level access controls

# Temporary workaround: Block access to Uncanny Automator plugin directory via .htaccess
# Add to WordPress root .htaccess file until patch is applied

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_URI} ^/wp-content/plugins/uncanny-automator/ [NC]
    RewriteCond %{REMOTE_ADDR} !^192\.168\.1\.100$
    RewriteRule .* - [F,L]
</IfModule>

# Note: Replace 192.168.1.100 with your admin IP address
# This is a temporary measure - apply the official patch as soon as possible
