CVE-2025-58703

Vulnerability

Overview The Skyword API Plugin for WordPress versions up to 2.5.3 suffers from a Stored Cross-Site Scripting (XSS) vulnerability due to improper neutralization of input during web page generation [1]. This allows an attacker to inject malicious scripts that are stored on the server and executed when other users access the affected page.

Exploitation

An attacker with low privileges (e.g., subscriber) can inject a script payload via the plugin's input fields. Successful exploitation requires an administrator or other privileged user to perform an action such as clicking a link, visiting a crafted page, or submitting a form that triggers the stored payload [1]. No special network position is needed; the attack can be launched remotely.

Impact

If exploited, the attacker can execute arbitrary JavaScript in the context of the victim's browser. This can lead to site defacement, redirection to malicious sites, injection of advertisements, or theft of sensitive information like cookies and session tokens [1]. Such vulnerabilities are often used in mass-exploit campaigns targeting thousands of sites.

Mitigation

Users are strongly advised to update the Skyword API Plugin to a version later than 2.5.3. If updating is not immediately possible, contact your hosting provider or web developer for assistance [1]. No workarounds are provided besides updating.
