Description OSIDB Bzimport 2026-11-10 13:05:23 UTC 
Tasmota through 16.0.0, fixed in commit 1cb7ebc, contains a cross-site request forgery vulnerability that allows unauthenticated attackers to bypass Referer-based CSRF protection in HttpCheckPriviledgedAccess() by crafting a Referer header where the device hostname or IP appears as a substring immediately after http://.evil.com/. Attackers can lure an administrator on the device's network to a malicious page to issue arbitrary console commands and reconfigure Wi-Fi, MQTT, settings, or firmware on devices lacking a WebPassword.
