CVE-2026-100311 Details
Description
A vulnerability was identified in mathurvishal CloudClassroom-PHP-Project up to 5dadec098bfbbf3300d60c3494db3fb95b66e7be. The affected element is an unknown function of the file managevideos2.php of the component Faculty Video Management. Such manipulation of the argument V_Title/V_Url/V_Remarks leads to cross site scripting. The attack may be performed from remote. The exploit is publicly available and might be used. This product utilizes a rolling release system for continuous delivery, and as such, version information for affected or updated releases is not disclosed. The vendor was contacted early about this disclosure but did not respond in any way.
A stored cross-site scripting vulnerability has been identified in the CloudClassroom PHP Project, specifically in version 1.0, prior to the commit 5dadec098bfbbf3300d60c3494db3fb95b66e7be. The issue resides in the Faculty Video Management component, within the 'managevideos2.php' file. The vulnerability allows authenticated attackers to inject arbitrary HTML and JavaScript into the 'V_Title', 'V_Url', and 'V_Remarks' fields. This injected content is then stored in the database and executed in the context of the user when the page is viewed, potentially leading to session hijacking and other malicious actions.
Users are advised to encode all output from user inputs using 'htmlspecialchars()' or a similar function, validate input on the server side, and implement a Content Security Policy. When rich-text input is necessary, HTML should be sanitized before processing.
