CVE-2026-55690 is a stored cross-site scripting vulnerability in the StarCitizenWiki EmbedVideo extension. According to the provided advisory, the issue is caused by unsanitized service names being reflected into HTML error messages. An attacker able to edit wiki content can supply a crafted service name via EmbedVideo parser functionality such as {{#ev:}} or {{#evl:}}, causing attacker-controlled HTML/JavaScript to be stored in page content and rendered to subsequent visitors in the wiki origin.
