Impact
The Video Url WordPress plugin contains a reflected XSS flaw that allows arbitrary script injection via the 'id' query parameter. An unauthenticated attacker can craft a malicious link that, when visited by a user, causes the browser to execute the injected script in the context of the site.
Affected Systems
WordPress installations that have the Video Url plugin installed in any version up to and including 1.0.0.3 are affected. Sites running older releases that have not applied the fix remain vulnerable.
Risk and Exploitability
The CVSS base score is 6.1, indicating moderate severity. The EPSS score of less than 1% suggests a low probability of exploitation at present. This vulnerability is not listed in the CISA KEV catalog. Exploitation requires only an unauthenticated user to click a crafted URL; no authentication or administrative privileges are needed.
