  1. CVE-2026-40597 7.6 Élevée

    mantisbt

    Mantis Bug Tracker (MantisBT) is an open source issue tracker. In versions 2.28.1 and below, given any pre-existing XSS / HTML injection vulnerability, an attacker can bypass the Content Security Policy's script-src directive by uploading a crafted attachment to any issue that, when accessed via the file_download.php link, will be downloaded with a valid JavaScript MIME type resulting in script execution. The uploaded payload must be sniffed as a valid JavaScript MIME type by PHP finfo (see file_create_finfo() API function). Non-JavaScript MIME types will not get imported in a <script> tag by the browser, due to response header X-Content-Type-Options being set to nosniff, which requires all imported JavaScript files to be a valid JavaScript MIME type. This issue has been fixed in version 2.28.2.

  2. CVE-2026-7615 4.3 Moyenne

    kasparsd Widget Context

    The Widget Context plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.3.3. This is due to missing or incorrect nonce validation on the save_widget_context_settings function. This makes it possible for unauthenticated attackers to modify widget visibility context settings stored in the WordPress options table via a forged POST request to /wp-admin/widgets.php via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

  3. CVE-2026-7879 5.3 Moyenne

    Concrete CMS · Concretecms concrete cms

    In Concrete CMS 9.5.0 and below,  the submit_password() method in concrete/controllers/single_page/download_file.php allows unauthorized file access since downloading permission-restricted files bypasses the view_file permission check. Files without passwords can be downloaded and any user who knows a file's password can download a password protected file regardless of whether they have permission to access the file. The Concrete CMS security team gave this vulnerability a CVSS v.4.0 score of 6.3 with vector CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N.  Thanks Youssef Eid for reporting
