In versions 0.19.1 and prior, the asset delivery handler serves uploaded files inline and relies on magic-byte detection for content type, which does not identify text-based formats such as HTML, SVG, or XHTML. These files are served with an empty Content-Type, no X-Content-Type-Options: nosniff header, and inline disposition, allowing browsers to sniff and render active content. An authenticated user can upload an HTML or SVG file containing JavaScript as a note asset, and when a victim navigates to the asset URL, the script executes under the application's origin with access to the victim's authenticated session and API actions. This issue has been fixed in version 0.19.2.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N","score":8.7,"severity":null}],"references":["https://github.com/enchant97/note-mark/security/advisories/GHSA-9pr4-rf97-79qh","https://github.com/enchant97/note-mark/commit/6bb62842ccb956870b9bf183629eba95e326e5e3","https://github.com/enchant97/note-mark/releases/tag/v0.19.2"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-23332","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Apr 16, 2026, 11:51:38 PM","dateUpdated":"Apr 18, 2026, 2:51:02 AM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
