CVE-2024-7426 is a vulnerability classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) found in the Community by PeepSo plugin for WordPress, which provides social networking, membership, registration, user profiles, and premium mobile app features. The vulnerability exists in all versions up to and including 6.4.6.0 due to the plugin's handling of errors and direct access to the sse.php file. When accessed, this file can cause the application to display error messages that reveal the full filesystem path of the web server hosting the WordPress site. This full path disclosure can provide attackers with valuable information about the server environment and directory structure, which can be leveraged to facilitate further attacks such as local file inclusion, remote code execution, or privilege escalation, especially if other vulnerabilities are present. The vulnerability does not require any authentication or user interaction, making it accessible to any remote attacker scanning for vulnerable sites. Despite the information disclosure being limited to path details and not directly exposing sensitive data like credentials or user information, it still constitutes a security risk. The CVSS v3.1 base score is 5.3, reflecting a medium severity due to the ease of exploitation and potential to aid in more damaging attacks. No public exploits have been reported so far, and no official patches are linked in the provided data, indicating that users should monitor vendor updates closely. The vulnerability is primarily a reconnaissance aid rather than a direct exploit vector but should be addressed promptly to reduce attack surface.

The primary impact of CVE-2024-7426 is the exposure of the full filesystem path of the web application to unauthenticated attackers. While this information disclosure does not directly compromise confidentiality, integrity, or availability, it significantly aids attackers in mapping the target environment. This can facilitate more sophisticated attacks such as local file inclusion, directory traversal, or remote code execution if other vulnerabilities exist. Organizations running the affected PeepSo plugin versions may face increased risk of targeted exploitation, especially if their WordPress installations are not otherwise hardened. The vulnerability could be leveraged in multi-stage attacks against social networking or membership sites, potentially leading to data breaches or service disruptions. Since the plugin is used in community and membership contexts, compromise could impact user privacy and trust. The medium severity rating reflects that while the flaw alone is not critical, it lowers the barrier for attackers to exploit other weaknesses, increasing overall risk.

To mitigate CVE-2024-7426, organizations should first check for and apply any official patches or updates released by PeepSo addressing this vulnerability. If patches are not yet available, administrators can implement the following specific measures: 1) Restrict direct access to the sse.php file by configuring web server rules (e.g., .htaccess or nginx config) to deny or limit access to this endpoint only to authenticated users or trusted IPs. 2) Disable detailed error message display in production environments by setting WordPress debugging and PHP error display settings to off, ensuring that error details are logged internally but not exposed to users. 3) Employ Web Application Firewalls (WAFs) to detect and block suspicious requests targeting sse.php or attempts to trigger error disclosures. 4) Conduct a thorough security audit of the WordPress environment to identify and remediate any additional vulnerabilities that could be chained with this information leak. 5) Monitor logs for unusual access patterns to sse.php or error messages indicating exploitation attempts. These targeted mitigations go beyond generic advice by focusing on controlling access to the vulnerable component and minimizing information exposure.
