Prior to 2026.9.1, wizard step Markdown supplied through the editor or imported bundles was evaluated by app/blueprints/wizard/routes.py in the application's non-sandboxed Jinja2 environment with application globals exposed. An authenticated user able to create steps, or an administrator importing an untrusted bundle through POST /settings/wizard/import, could execute arbitrary Python when GET /wizard/{server}/{idx} rendered the stored step; app/jinja_filters.py and app/services/wizard_widgets.py contained additional evaluation sinks. This could execute operating-system commands as the application user, disclose the Flask SECRET_KEY, access connected service credentials and the database, and produce stored cross-site scripting. This issue is fixed in 2026.9.1.\nhttps://www.cve.org/CVERecord?id=CVE-2026-108264https://github.com/wizarrrr/wizarr/security/advisories/GHSA-h9rv-mxh2-35f3https://github.com/wizarrrr/wizarr/commit/6aa3c33c1b3d945e055ef116cc531028b3735bb7https://github.com/wizarrrr/wizarr/releases/tag/v2026.9.1#wizarrrr #wizarr#CVE_2026_108264#bot", "creation_timestamp": "2026-10-09T20:59:59.358701Z"}, {"uuid": "38a47d07-7e5b-49f9-8703-ec5955e6dda6", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-108264", "type": "seen", "source": "https://bsky.app/profile/stemshop.bsky.social/post/3mxhydt4fuq22", "content": "\ud83d\udea8 CVE-2026-108264 \u2014 CVSS 9.1 CRITICAL\n\nWizarr is an advanced user invitation and management system for Jellyfin, Plex, Emby, and other media serve...\n\n\ud83d\udd0e https://stemshop.top/cve/CVE-2026-108264\n\n#CVE #CyberSecurity #InfoSec", "creation_timestamp": "2026-10-09T22:07:39.458689Z"}, {"uuid": "17818f1b-99ac-45b9-ba0e-66637053ad38", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-108264", "type": "seen", "source": "https://mastodon.social/users/hugovalters/statuses/117413452793328440", "content": "CVE-2026-108264 - Critical Jinja2 template injection RCE in Wizarr media user management.
