A vulnerability has been found in astralisone rive-mcp-server-core up to db1d0cc4cd52589116360428b7504fd0ca748b3e. This affects an unknown part of the file packages/mcp-server/src/tools/importRiveFile.ts of the component importRiveFile Flow. Such manipulation of the argument libraryId leads to path traversal. The attack needs to be performed locally. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. The project was informed of the problem early through an issue report but has not responded yet.
