CVE-2026-97347 Details
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.
A stored cross-site scripting vulnerability has been identified in the Post Views Stats Counter plugin for WordPress, affecting all versions through 1.1.7. The issue arises from inadequate input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary scripts that execute when users access the compromised pages. The plugin's sole input filter, which targets known bot signatures, can be easily circumvented by omitting those strings in the User-Agent payload.
No known patch is available. Users are advised to review the vulnerability details and consider uninstalling the affected plugin.
