Stored XSS in Editorial Rating – Product Review & Rating System WordPress Plugin

Publication date: 2026-06-30

Last updated on: 2026-06-30

Assigner: Wordfence

Description
The Editorial Rating – Product Review & Rating System plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'Link URL' Field in all versions up to, and including, 4.0.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The WordPress unfiltered_html capability exemption does not apply here because the payload is stored in post meta (_wpas_er_options via update_post_meta) rather than in post_content or post_excerpt, meaning the restriction affects all administrators regardless of their unfiltered_html status.

Executive Summary

The Editorial Rating – Product Review & Rating System plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) via the 'Link URL' field in all versions up to and including 4.0.5.

This vulnerability occurs because the plugin does not properly sanitize input or escape output, allowing authenticated users with administrator-level access or higher to inject malicious web scripts.

These injected scripts are stored in the post meta data and execute whenever a user accesses the affected page.

Notably, the usual WordPress unfiltered_html capability exemption does not apply here, meaning all administrators are affected regardless of their unfiltered_html status.

Impact Analysis

This vulnerability allows an attacker with administrator-level access to inject arbitrary scripts that execute in the context of users visiting the affected pages.

Such scripts can be used to steal sensitive information, hijack user sessions, perform actions on behalf of users, or spread malware.

Because the attack requires high privileges (administrator-level access), the risk is somewhat mitigated, but it still poses a significant threat to site integrity and user security.
