What is CVE-2025-58766?

A notable security flaw has been identified in the Dyad application which is a local AI app builder. The vulnerability affects version v0.19.0 and previous releases, allowing malicious actors to execute arbitrary code on devices running the application. The core issue lies within the application's preview window functionality, which can be exploited to bypass Docker container security measures. By creating malicious web content that executes automatically upon loading the preview, an attacker can penetrate the application's security layers, effectively gaining control of the affected system. Users are strongly advised to upgrade to Dyad v0.20.0 or later to mitigate this risk.

Affected Version(s)
