Stored XSS in Transliterator WordPress Plugin

Publication date: 2026-10-03

Last updated on: 2026-10-03

Assigner: Wordfence

Description
The Transliterator – Multilingual and Multi-script Text Conversion plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content via Predictable {rstr_keep} Placeholder in all versions up to, and including, 2.5.8 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload survives WordPress comment save-time sanitization because the tags and attributes used (such as a[title] and code) are permitted by the core comment kses allow-list, and the literal characters comprising the plugin's shortcode markers and placeholder tokens are not stripped.

Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) flaw in the Transliterator WordPress plugin. It allows unauthenticated attackers to inject malicious scripts into web pages via comment content. The issue occurs because the plugin uses predictable placeholders that bypass WordPress's comment sanitization. The injected scripts execute when users view the affected pages.

Detection Guidance

To detect this vulnerability, inspect WordPress comments for unusual content containing script tags or plugin shortcode markers like {rstr_keep}. Check for comments with attributes such as a[title] or code tags that may indicate malicious payloads.

Impact Analysis

If you use the vulnerable plugin, attackers could steal user sessions, redirect to malicious sites, or deface your website. Visitors to your site may have their data compromised if they interact with the injected scripts. The attack requires no authentication, making it easier for remote attackers to exploit.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR or HIPAA if user data is exposed due to the XSS attack. GDPR requires protecting personal data, and HIPAA mandates safeguarding sensitive health information. A successful exploit may result in data breaches, triggering regulatory penalties and legal consequences.

Mitigation Strategies

Update the Transliterator plugin to the latest version beyond 2.5.8. Review and remove suspicious comments containing script tags or unusual shortcode markers. Consider disabling comments temporarily until the plugin is updated.
