Assigner: GitHub_M
Reserved: 13.01.2026 Published: 23.03.2026 Updated: 23.03.2026

Blinko is an AI-powered card note-taking project. In versions from 1.8.3 and prior, the fileName parameter is not filtered, allowing path traversal to write files anywhere on the file system. Moreover, this interface only requires authProcedure (normal user), not superAdminAuthMiddleware. At time of publication, there are no publicly available patches.
