At a glance

CVE-2025-13377 is a critical-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the 10Web Booster WordPress plugin, affecting versions <= 2.32.7. It carries a CVSS score of 9.6 (reachable over the network; low attack complexity; high integrity, availability impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 2.32.11; sites on affected versions should update now. Disclosed December 2025, reported by shark3y.

Vulnerability Overview

The 10Web Booster – Website speed optimization, Cache & Page Speed optimizer plugin for WordPress is vulnerable to arbitrary folder deletion due to insufficient file path validation in the get_cache_dir_for_page_from_url() function in all versions up to, and including, 2.32.7. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary folders on the server, which can easily lead to a loss of data or a denial of service condition.

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 integrity, availability.

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

10Web Booster <= 2.32.7 carries this weakness at get_cache_dir_for_page_from_url(), and reaching it takes an account at Subscriber 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 10Web Booster the fix is 2.32.11: builds <= 2.32.7 are affected, anything from 2.32.11 onward is not.

Remediation

Update to version 2.32.11, or a newer patched version

How does WordSec protect against this?

An attacker needs Subscriber 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: 10Web Booster 2.32.11 closes this, and updating the plugin is the step that ends it.
