CVE-2025-64711Public exploit

Session script execution via HTML-rendered filenames

Published Nov 13, 2025 · Updated Nov 13, 2025

Cross-site scripting in PrivateBin 1.7.7 through 2.0.2 allows local users to execute script by dropping a crafted file. AttachmentViewer.printDragAndDropFileNames joins attacker-controlled filenames with break tags and passes the result to jQuery .html(), treating each filename as markup. Exploitation requires file uploads, a macOS or Linux victim who attaches the file, and disabled CSP for JavaScript; otherwise, injected HTML can redirect or phish only that session.
