The Skyword API Plugin for WordPress contains a stored cross-site scripting vulnerability (CWE-79) in its 'skyword_iframe' shortcode due to improper neutralization of input during web page generation. This allows authenticated users with contributor-level permissions or higher to inject malicious scripts via user-supplied shortcode attributes. These scripts execute in the context of any user who accesses the compromised page, potentially leading to information disclosure or session hijacking. The vulnerability affects all plugin versions up to 2.5.2. There is no vendor advisory or patch link available at this time.

An attacker with contributor-level access or higher can exploit this vulnerability to inject and store malicious scripts that execute in the browsers of users viewing the affected pages. This can lead to limited confidentiality and integrity impacts, such as theft of user session data or manipulation of page content. There is no indication of availability impact. The vulnerability requires authenticated access and does not require user interaction beyond viewing the injected page.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the Skyword API Plugin if possible. Monitor for plugin updates and apply any official patches promptly once available.
