At a glance

CVE-2026-17505 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the TranslatePress WordPress plugin, affecting versions <= 3.2.5. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 3.2.6; sites on affected versions should update now. Disclosed August 2026, reported by momopon1415.

Vulnerability Overview

The Translate Multilingual sites – TranslatePress plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 's' parameter in versions up to, and including, 3.2.5. This is due to the translate_page() function unconditionally replacing the plugin's internal #!trpst# and #!trpen# marker tokens with literal angle brackets across the entire HTML page output after WordPress has already sanitized and escaped user input — allowing the attacker to bypass WordPress's normal HTML escaping by using these tokens, which are not HTML special characters, in the search query. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a specially crafted link.

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 privileges on the target site.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

TranslatePress <= 3.2.5 carries this weakness at translate_page(), and reaching it takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For TranslatePress the fix is 3.2.6: builds <= 3.2.5 are affected, anything from 3.2.6 onward is not.

Remediation

Update to version 3.2.6, or a newer patched version

How WordSec helps

The attempt arrives as an ordinary request to TranslatePress: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: TranslatePress 3.2.6 closes this, and updating the plugin is the step that ends it.
