CVE-2022-46165

Syncthing is an open source, continuous file synchronization program. In
versions prior to 1.23.5 a compromised instance with shared folders could
sync malicious files which contain arbitrary HTML and JavaScript in the
name. If the owner of another device looks over the shared folder settings
and moves the mouse over the latest sync, a script could be executed to
change settings for shared folders or add devices automatically.
Additionally adding a new device with a malicious name could embed HTML or
JavaScript inside parts of the page. As a result the webUI may be subject
to a stored cross site scripting attack. This issue has been addressed in
version 1.23.5. Users are advised to upgrade. Users unable to upgrade
should avoid sharing folders with untrusted users.
