CVE-2026-39469: PageLayer Information Disclosure Flaw

CVE-2026-39469 Overview

CVE-2026-39469 is a Sensitive Data Exposure vulnerability in the Softaculous PageLayer WordPress plugin. The vulnerability is classified under CWE-497 (Exposure of Sensitive System Information to an Unauthorized Control Sphere), which allows attackers to retrieve embedded sensitive data from affected WordPress installations.

This information disclosure flaw enables unauthorized parties to access sensitive system information that should be protected. The vulnerability exists in the PageLayer plugin, a popular WordPress page builder used for creating responsive websites.

Critical Impact

Unauthorized actors can extract sensitive system information from WordPress sites running vulnerable versions of PageLayer, potentially exposing configuration data, internal paths, and other protected information.

Affected Products

• Softaculous PageLayer plugin versions through 2.0.8
• WordPress installations using the affected PageLayer versions

Technical Details for CVE-2026-39469

Vulnerability Analysis

This vulnerability falls under the category of Sensitive Data Exposure, specifically involving the exposure of system information to unauthorized control spheres. The PageLayer WordPress plugin fails to properly restrict access to sensitive system information, allowing attackers to retrieve embedded data that should be protected.

The vulnerability permits attackers to access sensitive configuration or system details that are embedded within the plugin's functionality. This type of information leakage can provide attackers with valuable reconnaissance data for further attacks or direct access to sensitive information stored within the WordPress installation.

Root Cause

The root cause is improper access control within the PageLayer plugin that fails to adequately protect sensitive system information from unauthorized access. The plugin exposes sensitive data to users or control spheres that should not have access to this information, violating the principle of least privilege and proper data protection controls.

This weakness (CWE-497) occurs when the application exposes sensitive system information to an actor that is not explicitly authorized to have access to that information. In the context of a WordPress plugin, this could involve exposing internal paths, configuration settings, database credentials, or other sensitive data through improperly secured endpoints or functions.

Attack Vector

The attack vector for this vulnerability involves an attacker targeting a WordPress installation running a vulnerable version of PageLayer (2.0.8 or earlier). The attacker can exploit the improper access controls to retrieve sensitive embedded data without proper authorization.

The attack does not require sophisticated techniques—an attacker simply needs to identify a vulnerable installation and access the improperly protected sensitive information. This could be accomplished through direct requests to vulnerable endpoints or by exploiting the plugin's data handling mechanisms.

Detection Methods for CVE-2026-39469

Indicators of Compromise

• Unusual access patterns to PageLayer plugin endpoints or files
• Unexpected outbound data transfers containing system configuration information
• Anomalous requests targeting PageLayer-specific paths or parameters
• Evidence of reconnaissance activity against WordPress plugin directories

Detection Strategies

• Monitor web application logs for suspicious requests to PageLayer plugin endpoints
• Implement Web Application Firewall (WAF) rules to detect information disclosure attempts
• Review access logs for unauthorized attempts to access plugin configuration data
• Deploy endpoint detection to identify unusual data exfiltration patterns

Monitoring Recommendations

• Enable detailed logging for WordPress and the PageLayer plugin
• Configure alerting for unusual access patterns to plugin directories
• Implement file integrity monitoring for PageLayer plugin files
• Monitor for unexpected changes to plugin configuration or behavior

How to Mitigate CVE-2026-39469

Immediate Actions Required

• Update PageLayer plugin to the latest available version beyond 2.0.8
• Audit WordPress installations to identify all instances running vulnerable PageLayer versions
• Review access logs for evidence of exploitation attempts
• Consider temporarily disabling the PageLayer plugin until patched

Patch Information

Organizations should update the PageLayer WordPress plugin to a version newer than 2.0.8 as soon as a patched version becomes available. Check the official WordPress plugin repository or the Patchstack advisory for the latest security updates.

Workarounds

• Implement additional access controls at the web server level to restrict access to sensitive plugin endpoints
• Use a Web Application Firewall (WAF) to filter potentially malicious requests
• Restrict access to the WordPress admin area to trusted IP addresses only
• Consider using security plugins to add additional protection layers until a patch is available

# Example: Restrict access to plugin directory via .htaccess
# Add to WordPress root .htaccess or plugin directory

<IfModule mod_rewrite.c>
  RewriteEngine On
  # Block direct access to plugin sensitive files
  RewriteRule ^wp-content/plugins/pagelayer/.*\.(php|inc)$ - [F,L]
</IfModule>

# Alternative: Restrict by IP (replace with your admin IP)
<FilesMatch "\.(php|inc)$">
  Require ip 192.168.1.0/24
</FilesMatch>
