CVE-2026-109823

Host filesystem path disclosure via DNS rebinding

Published Oct 27, 2026 CVSS 4.0 · 2.3 Low EPSS < 1% KEV · Not listed
Description
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.
