Details

blob42 gosuki through commit 6e2bf34 contains a Stored Cross-Site Scripting (XSS) vulnerability. The application uses text/template instead of html/template, failing to perform context-aware auto-escaping on the URL and DisplayURL fields of bookmarks in internal/webui/templates/bookmarks.html. An attacker can craft a malicious bookmark URL containing HTML attribute-breaking payloads that execute arbitrary JavaScript in the victim's browser context when rendered in the local web interface.
