Detailsinfo

A vulnerability has been found in tauri-apps plugins-workspace up to 2.2.0 on Linux and classified as very critical. This vulnerability affects some unknown functionality of the component Open Endpoint. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The Tauri shell plugin allows access to the system shell. Prior to 2.2.1, the Tauri shell plugin exposes functionality to execute code and open programs on the system. The open endpoint of this plugin is designed to allow open functionality with the system opener (e.g. xdg-open on Linux). This was meant to be restricted to a reasonable number of protocols like https or mailto by default. This default restriction was not functional due to improper validation of the allowed protocols, allowing for potentially dangerous protocols like file://, smb://, or nfs:// and others to be opened by the system registered protocol handler. By passing untrusted user input to the open endpoint these potentially dangerous protocols can be abused to gain remote code execution on the system. This either requires direct exposure of the endpoint to application users or code execution in the frontend of a Tauri application. This vulnerability is fixed in 2.2.1.

The advisory is shared for download at github.com. This vulnerability was named CVE-2025-31477 since 03/28/2025. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx.
