Vulnerability Title
calibre has a Path Traversal Leading to Arbitrary File Write and Potential Code Execution
Source: NVD (National Vulnerability Database)
Vulnerability Description
calibre is an e-book manager. Prior to 9.2.0, Calibre's CHM reader contains a path traversal vulnerability that allows arbitrary file writes anywhere the user has write permissions. On Windows (haven't tested on other OS's), this can lead to Remote Code Execution by writing a payload to the Startup folder, which executes on next login. This vulnerability is fixed in 9.2.0.
