CVE-2026-97347Post Views Stats Counter <= 1.1.7 - Unauthenticated Stored Cross-Site Scripting via User-Agent Header
High 7.2
In plain English
A high-severity cross-site scripting in Post Views Stats Counter from kazukiyanamoto. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 25% of all known vulnerabilities). Ready-made attack tooling exists: public proof-of-concept code.
Official 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.
