CVE-2025-25114

The User Role plugin for WordPress versions up to and including 1.0 is vulnerable to reflected cross-site scripting (XSS) due to improper neutralization of user-supplied input during web page generation [1]. This flaw enables an attacker to inject arbitrary HTML and JavaScript code into a web page, which is then executed in the browser of an unsuspecting user.

Exploitation requires user interaction, such as clicking a specially crafted link or visiting a maliciously prepared page [1]. The attacker must trick a privileged user (e.g., an administrator) into performing the action, as the vulnerability is reflected and not stored. This limitation reduces the attack surface but still poses a significant risk if an administrator can be socially engineered.

Successful exploitation allows the attacker to execute arbitrary scripts in the context of the victim's browser session. This can lead to session hijacking, defacement, redirection to malicious sites, or the injection of advertisements and other unwanted content [1]. The CVSS score of 7.1 (High) reflects the potential for impact, though the official advisory notes that the vulnerability is considered low severity for WordPress and unlikely to be exploited [1].

As a mitigation, users are strongly advised to update the User Role plugin to a patched version if available [1]. If an update is not yet released, a Web Application Firewall (WAF) or the Patchstack mitigation rule can block attacks until an official patch is applied [1]. Given the active threat landscape, immediate action is recommended to prevent exploitation.
