Vikunja Desktop allows arbitrary local application invocation via unvalidated shell.openExternal
Summary
Vikunja Desktop allows arbitrary local application invocation via unvalidated shell.openExternal
Original description
The description as published by the source.
Vikunja is an open-source self-hosted task management platform. Starting in version 0.21.0 and prior to version 2.2.0, the Vikunja Desktop Electron wrapper passes URLs from window.open() calls directly to shell.openExternal() without any validation or protocol allowlisting. An attacker who can place a link with target="_blank" (or that otherwise triggers window.open) in user-generated content can cause the victim's operating system to open arbitrary URI schemes, invoking local applications, opening local files, or triggering custom protocol handlers. Version 2.2.0 patches the issue.
