Low risk13th percentile - higher than 13% of all known CVEs
Summary
The NewStatPress plugin for WordPress in versions up to and including 1.4.3 is vulnerable to Stored Cross-Site Scripting via a regex bypass in the `nsp_shortcode` function due to insufficient input sanitization and output escaping on user-supplied attributes. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts that execute when a user visits the injected page.
Risk Assessment
An attacker can execute arbitrary JavaScript in the victim's browser, potentially leading to session theft, redirects, or other attacks in the context of the site.
Recommendation
Update the NewStatPress plugin to a version newer than 1.4.3 as soon as it becomes available, and in the meantime limit the number of accounts with Contributor privileges.
Other vulnerabilities in NewStatPress
See all- CVE-2026-101924High
The NewStatPress plugin for WordPress up to version 1.4.5 is vulnerable to Stored Cross-Site Scripting via the 'Last referrers' meta box on the Overview admin page due to insufficient output escaping, allowing unauthenticated attackers to inject arbitrary scripts.
- CVE-2026-100153High
The NewStatPress plugin for WordPress in versions up to and including 1.4.5 is vulnerable to Stored Cross-Site Scripting via the 'QUERY_STRING / REQUEST_URI' parameter. Due to insufficient input sanitization and output escaping, an unauthenticated attacker can inject arbitrary scripts into pages that execute when a user visits the injected page. Exploitation requires that an administrator has placed the [NewStatPress type="Top Pages"] shortcode on a publicly viewable page, and that the attacker's crafted URL accumulates enough hits to appear in the top-N ranking.
- CVE-2026-14845Medium
The NewStatPress WordPress plugin before version 1.4.5 does not sanitize and escape data from unauthenticated visitor requests before storing and later outputting it in one of its widgets. This allows unauthenticated attackers to perform Stored Cross-Site Scripting attacks against users viewing the affected widget.
Original NVD description (English source)
The NewStatPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via a regex bypass in nsp_shortcode function in all versions up to, and including, 1.4.3 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
