CVE-2025-23468

Vulnerability

CVE-2025-23468 is a reflected Cross-Site Scripting (XSS) vulnerability in the Essay Wizard (wpCRES) plugin for WordPress, identified as improper neutralization of user input during web page generation. The flaw exists in versions up to and including 1.0.6.4, allowing an unauthenticated attacker to inject malicious scripts via crafted HTTP requests.

Exploitation

Exploitation does not require authentication, but successful execution relies on user interaction—the victim must click a specially crafted link or visit a maliciously crafted page. The vulnerable parameter is not explicitly documented, but the reflected nature means the injected payload is echoed back in the HTTP response without proper sanitization, enabling script execution in the victim's browser.

Impact

An attacker can inject arbitrary HTML and JavaScript payloads, leading to potential redirects, ad injections, content modification, or theft of sensitive data such as session cookies. The CVSS v3 score of 7.1 (High) reflects the moderate impact but ease of exploitation in a WordPress context, where such vulnerabilities are often targeted in mass campaigns.

Mitigation

The vendor has issued a mitigation rule through Patchstack to block attacks until an official patch is available. Immediate action required: update the plugin to a patched version when released, or apply a web application firewall rule. If unable to update, consider temporarily disabling the plugin or consulting a security professional [1].
