Description

Blinko is an AI-powered card note-taking project. In versions from 1.8.3 and prior, the plugin file server endpoint uses join() to concatenate paths but does not verify if the final path is within the plugins directory, leading to path traversal. At time of publication, there are no publicly available patches.
