Vulnerability Overview

TablePress prior to version 1.8.1 allows an attacker to conduct XML External Entity (XXE) attacks via unspecified vectors.

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-611: Improper Restriction of XML External Entity Reference

The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.

Remediation

Update to version 1.8.1, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to TablePress: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: TablePress 1.8.1 closes this, and updating the plugin is the step that ends it.
