Description
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.
Analysis
Blinko versions 1.8.3 and earlier allow authenticated users to write arbitrary files to the filesystem through an unvalidated fileName parameter, exploiting a path traversal weakness. The vulnerability requires only basic user authentication and can be leveraged to place malicious files anywhere on the server, potentially leading to remote code execution or system compromise. …
