Directory Traversal in WP Encryption WordPress Plugin

Publication date: 2026-07-23

Last updated on: 2026-07-23

Assigner: Wordfence

Description
The WP Encryption – One Click Free SSL Certificate & SSL / HTTPS Redirect, Security & SSL Scan plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 7.8.6.6 via the 'imploded' parameter parameter. This makes it possible for authenticated attackers, with administrator-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information. Although file write content is passed through esc_html(), which encodes angle brackets and prevents direct PHP execution, plaintext configuration files such as .htaccess are fully writable and exploitable for denial-of-service or redirect attacks.

Executive Summary

This vulnerability is a Directory Traversal issue in the WP Encryption WordPress plugin up to version 7.8.6.6. It allows authenticated attackers with administrator access or higher to read arbitrary files on the server by exploiting the 'imploded' parameter. This can expose sensitive information stored in files.

Detection Guidance

Check for unauthorized file access or modifications in WordPress directories. Review server logs for suspicious activity related to the 'imploded' parameter in the WP Encryption plugin. Use commands like grep to search for file reads or writes in plugin logs or web server access logs.

Impact Analysis

If exploited, this vulnerability could allow attackers to access sensitive files on your server, such as configuration files or stored data. This may lead to data breaches, unauthorized access, or further attacks like denial-of-service or website redirects if plaintext files like .htaccess are modified.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR or HIPAA if sensitive personal or health data is exposed. Unauthorized access to files may violate data protection requirements, potentially resulting in legal penalties, fines, or reputational damage.

Mitigation Strategies

Update the WP Encryption plugin to the latest version if available. Remove or disable the plugin if no update is available. Restrict administrator-level access to only trusted users. Monitor server files for unauthorized changes, especially .htaccess files.
