The ONLYOFFICE Docs plugin for WordPress contains a Stored Cross-Site Scripting vulnerability (CVE-2024-11450) affecting all versions up to and including 2.0.0.

The vulnerability stems from improper neutralization of input during web page generation, specifically in the handling of user-supplied attributes in the 'onlyoffice' shortcode (NVD).

When successfully exploited, this vulnerability allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages. These malicious scripts will execute whenever any user accesses the compromised page (NVD).
