Malicious input supplied to the Box[title] and box[url] parameters can be rendered unfiltered, enabling an attacker to inject arbitrary client\u2011side code that runs in the browser of users visiting the affected page.

Although no EPSS score is available, the CVSS score of 6.1 indicates a moderate risk, and the vulnerability is not yet recorded in the CISA Known Exploited Vulnerabilities catalog. If abused, the impact could be persistent client\u2011side compromise for all users who view the malicious content."}}}}, "created": "2026-04-10T08:53:59.772754+00:00", "title": "Cross\u2011Site Scripting in LimeSurvey Box Parameters Allows Remote Code Execution", "updated": "2026-04-10T09:33:09.741985+00:00", "vendors": ["limesurvey", "limesurvey$PRODUCT$limesurvey"]}
