CVE-2026-109823
CVE-2026-109823 · Host filesystem path disclosure via DNS rebinding
This page contains facts from public vulnerability sources. Check the original advisory before updating.
An attacker can read the name of filesystem paths of your application present via Tidewave configuration via /tidewave/connect or via the rendered toolbar. Neither response checks the Host header. A web page that rebinds its own domain to the loopback address can therefore read the tag with a same-origin request, which carries no Origin header. The paths usually reveal the local username and the project layout. This issue affects tidewave: from 0.8.0 before 0.9.2.
