CVE-2025-64258: Follow My Blog Post Info Disclosure Flaw

CVE-2025-64258 Overview

CVE-2025-64258 is a Sensitive Data Exposure vulnerability affecting the Follow My Blog Post WordPress plugin developed by wpwebelite. This vulnerability allows unauthorized actors to retrieve embedded sensitive system information from affected WordPress installations. The flaw stems from improper exposure of sensitive system information to an unauthorized control sphere (CWE-497), enabling attackers to access confidential data without authentication.

Critical Impact

Unauthenticated attackers can remotely access sensitive system information embedded within the plugin, potentially exposing confidential configuration data, user information, or other sensitive details that could be leveraged for further attacks.

Affected Products

• wpwebelite Follow My Blog Post versions up to and including 2.3.9
• WordPress installations with vulnerable Follow My Blog Post plugin installed
• All configurations of the affected plugin versions are impacted

Technical Details for CVE-2025-64258

Vulnerability Analysis

This vulnerability falls under CWE-497 (Exposure of Sensitive System Information to an Unauthorized Control Sphere), indicating that the Follow My Blog Post plugin exposes internal system details to entities outside the intended security boundary. The vulnerability is remotely exploitable over the network without requiring authentication or user interaction. An attacker successfully exploiting this vulnerability could retrieve sensitive data that is embedded within the plugin's functionality or responses.

The vulnerability enables complete compromise of confidentiality for the affected data, though it does not directly impact system integrity or availability. This type of information disclosure can serve as a reconnaissance tool for attackers, providing valuable details that could facilitate subsequent attacks against the WordPress installation or its underlying infrastructure.

Root Cause

The root cause of this vulnerability lies in improper access controls within the Follow My Blog Post plugin. Sensitive system information is inadvertently exposed to unauthorized parties due to insufficient validation of request authorization. The plugin fails to properly restrict access to internal data that should only be available to authenticated administrators.

Attack Vector

The vulnerability is exploitable via network-based attacks with low complexity. An unauthenticated remote attacker can craft requests to the WordPress site running the vulnerable plugin to retrieve sensitive embedded data. The attack requires no privileges and no user interaction, making it trivial to exploit at scale against vulnerable WordPress installations.

The attack flow typically involves:

1. Identifying WordPress sites running the Follow My Blog Post plugin
2. Sending crafted requests to endpoints that expose sensitive information
3. Extracting confidential data from the plugin's responses

For technical details on the specific exploitation mechanism, refer to the Patchstack Vulnerability Report.

Detection Methods for CVE-2025-64258

Indicators of Compromise

• Unusual HTTP requests targeting Follow My Blog Post plugin endpoints
• Unexpected access patterns to plugin-specific URLs from external IP addresses
• Log entries showing unauthenticated requests attempting to access plugin functionality
• Evidence of reconnaissance activity against WordPress plugin directories

Detection Strategies

• Monitor web server access logs for suspicious requests to /wp-content/plugins/follow-my-blog-post/ paths
• Implement Web Application Firewall (WAF) rules to detect and block anomalous plugin access patterns
• Deploy file integrity monitoring on WordPress plugin directories to detect unauthorized changes
• Review WordPress security logs for failed authentication attempts followed by direct plugin access

Monitoring Recommendations

• Enable verbose logging for WordPress and the Follow My Blog Post plugin
• Configure alerting for unexpected spikes in requests to plugin endpoints
• Implement real-time monitoring of outbound data transfers from WordPress installations
• Conduct regular WordPress plugin audits to identify outdated or vulnerable components

How to Mitigate CVE-2025-64258

Immediate Actions Required

• Update the Follow My Blog Post plugin to a version newer than 2.3.9 when a patched version becomes available
• Consider temporarily disabling the Follow My Blog Post plugin if it is not essential to site functionality
• Review WordPress access logs for evidence of prior exploitation attempts
• Audit sensitive data that may have been exposed through the vulnerable plugin

Patch Information

At the time of publication, organizations should monitor the WordPress plugin repository and the vendor's communications for security updates. Check the Patchstack Vulnerability Report for the latest patch status and remediation guidance.

Workarounds

• Implement IP-based access restrictions to limit access to WordPress admin and plugin directories
• Deploy a Web Application Firewall with rules to block suspicious requests to the vulnerable plugin
• Disable the Follow My Blog Post plugin temporarily until a security patch is released
• Restrict access to sensitive WordPress endpoints using .htaccess or server configuration rules

# Example .htaccess restriction for plugin directory
<Directory "/var/www/html/wp-content/plugins/follow-my-blog-post">
    Order Deny,Allow
    Deny from all
    Allow from 127.0.0.1
    Allow from YOUR_ADMIN_IP
</Directory>
