Stored XSS in Post Views Stats Counter WordPress Plugin

Publication date: 2026-09-30

Last updated on: 2026-09-30

Assigner: Wordfence

Description
The Post Views Stats Counter plugin for WordPress is vulnerable to Stored Cross-Site Scripting via User-Agent Header in all versions up to, and including, 1.1.7 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 plugin's only input filter is a substring blacklist for known bot signatures (e.g. 'bot', 'spider', 'crawler'), which can be trivially bypassed by crafting a User-Agent payload that omits those strings.

Executive Summary

The Post Views Stats Counter WordPress plugin up to version 1.1.7 has a stored cross-site scripting vulnerability due to insufficient input sanitization and output escaping in the User-Agent header. Attackers can inject malicious scripts that execute when users access infected pages. The plugin only blocks known bot signatures, which can be bypassed easily.

Impact Analysis

Unauthenticated attackers can inject arbitrary web scripts into pages. When users visit these pages, the injected scripts execute, potentially stealing cookies, session tokens, or other sensitive data. This could lead to account takeovers or unauthorized actions on behalf of users.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR's data protection principles or HIPAA's security requirements for protected health information. Organizations may face compliance penalties if user data is compromised through this exploit.

Mitigation Strategies

Update the Post Views Stats Counter plugin to the latest version beyond 1.1.7 to patch the vulnerability. If an update is not available, consider disabling or removing the plugin immediately to prevent exploitation.
