CVE-2026-55592: LISSY93 Dashy

Low severity, CVSS 3.9. EPSS: 0.3% chance of exploitation in the next 30 days.

Dashy is a self-hostable personal dashboard. Prior to 4.3.7, Dashy's workspace view trusts the url query parameter and assigns it directly to an iframe source without scheme validation. If a logged-in user opens a crafted workspace link containing a javascript: URL, JavaScript runs on the Dashy origin and can read same-origin browser data, interact with the Dashy DOM, and send requests as the victim. This issue is fixed in version 4.3.7.
