At a glance

CVE-2024-47637 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the LiteSpeed Cache WordPress plugin, affecting versions <= 6.4.1. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Author level or above. The issue is fixed in version 6.5.1; sites on affected versions should update now. Disclosed September 2024, reported by TaiYou.

Vulnerability Overview

The LiteSpeed Cache plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 6.4.1. This makes it possible for authenticated attackers, with author-level access and above, to perform actions on files outside of the originally intended directory.

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.

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

Reaching this weakness in LiteSpeed Cache <= 6.4.1 takes an account at Author 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 LiteSpeed Cache the fix is 6.5.1: builds <= 6.4.1 are affected, anything from 6.5.1 onward is not.

Remediation

Update to version 6.5.1, or a newer patched version

How does WordSec protect against this?

An attacker needs Author 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: LiteSpeed Cache 6.5.1 closes this, and updating the plugin is the step that ends it.
