## Technical details

The vulnerability is a DOM-based cross-site scripting (CWE-79) flaw that allows XSS through the USE element in SVG documents. The vulnerable component is the SVG tag support in the editor, which fails to properly sanitize or restrict SVG-based markup. The attack vector is network-based and requires user interaction (opening a malicious SVG document). An attacker can execute arbitrary JavaScript in the context of the Joplin application, potentially stealing notes or session data. The vulnerability was patched in version 2.11.5 by disabling SVG tag support in the editor.
