Overview

CVE-2026-15786 is a medium-severity vulnerability. It was published on July 23, 2026 and has a CVSS 3.1 base score of 4.4 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.4, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical 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. This is only exploitable when the premium version of the software is enabled and active.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
