CVE-2022-4880
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability was found in stakira OpenUtau. It has been classified as critical. This affects the function VoicebankInstaller of the file OpenUtau.Core/Classic/VoicebankInstaller.cs of the component ZIP Archive Handler. The manipulation leads to path traversal. Upgrading to version 0.0.991 is able to address this issue. The identifier of the patch is 849a0a6912aac8b1c28cc32aa1132a3140caff4a. It is recommended to upgrade the affected component. The identifier VDB-217617 was assigned to this vulnerability.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisA file path is built from user input without being confined, so sequences like “../” let an attacker step outside the intended directory. That can expose configuration, credentials, or source code, and in the worst case lets an attacker write files where they shouldn't. A durable fix resolves and canonicalises the path, then rejects anything that escapes a known-safe base directory.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped0.0.991
0.0.991
- 1. Close the OpenUtau application if it is currently running
- 2. Download the latest release of OpenUtau version 0.0.991 or later from the official GitHub releases page
- 3. Verify the downloaded file integrity if possible (e.g., checksum verification)
- 4. Install the new version by running the installer or replacing the executable
- 5. Launch OpenUtau and verify the application functions normally
- 6. Test voicebank installation functionality to confirm the path traversal vulnerability is resolved
