CVE-2022-24833Public exploitNetwork attack vector

Script execution via unsanitized SVG preview

Published Apr 11, 2022 · Updated Apr 22, 2025

Cross-site scripting in PrivateBin before 1.4.0 allows remote attackers to execute JavaScript via a crafted SVG attachment. The attachment preview creates a blob URL from an unsanitized SVG, so opening the preview in a new tab executes embedded script in the site's origin. Exploitation requires enabled attachments, a missing or unsafe CSP, and victim interaction; script can access same-origin cookies or storage but not PrivateBin paste contents.
