CVE-2026-4083 identifies a Stored Cross-Site Scripting (XSS) vulnerability in the Scoreboard for HTML5 Games Lite plugin for WordPress, affecting versions up to and including 1.2. This medium-severity flaw (CVSS 6.4) allows authenticated attackers with Contributor-level access or higher to inject arbitrary web scripts. The vulnerability stems from the 'scoreboard' shortcode permitting JavaScript event handler attributes within rendered iframe elements, bypassing existing escaping functions. These injected scripts execute whenever a user accesses an affected page, potentially leading to client-side attacks. Currently, there is no evidence of active exploitation, public exploit code, or significant community discussion for this CVE.
