Summary

Tauri is software for building applications for multi-platform deployment. The Tauri IPC is usually strictly isolated from external websites, but in versions 1.0.0 until 1.0.9, 1.1.0 until 1.1.4, and 1.2.0 until 1.2.5, the isolation can be bypassed by redirecting an existing Tauri window to an external website. This is either possible by an application implementing a feature for users to visit arbitrary websites or due to a bug allowing the open redirect. This allows the external website access to the IPC layer and therefore to all configured and exposed Tauri API endpoints and application specific implemented Tauri commands. This issue has been patched in versions 1.0.9, 1.1.4, and 1.2.5. As a workaround, prevent arbitrary input in redirect features and/or only allow trusted websites access to the IPC.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of tauri-apps/tauri published their own advisory on GitHub. Reviewed sources take precedence over it.
