Description
Zipline before 4.0.2 contains a predictable filename vulnerability that allows attackers to infer other users' upload filenames by recovering the Math.random generator state. Attackers with five consecutive gfycat-style filenames can reconstruct the random state to predict previous and future filenames until the instance restarts, exposing private uploads.
