At a glance

CVE-2025-0859 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Post and Page Builder by BoldGrid WordPress plugin, affecting versions <= 1.27.6. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 1.27.7; sites on affected versions should update now. Disclosed February 2025, reported by mikemyers.

Vulnerability Overview

The Post and Page Builder by BoldGrid – Visual Drag and Drop Editor plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.27.6 via the template_via_url() function. This makes it possible for authenticated attackers, with Contributor-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Post and Page Builder by BoldGrid <= 1.27.6 carries this weakness at template_via_url(), and reaching it takes an account at Contributor level or above. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.

Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For Post and Page Builder by BoldGrid the fix is 1.27.7: builds <= 1.27.6 are affected, anything from 1.27.7 onward is not.

Remediation

Update to version 1.27.7, or a newer patched version

How does WordSec protect against this?

An attacker needs Contributor access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Post and Page Builder by BoldGrid 1.27.7 closes this, and updating the plugin is the step that ends it.
