| Doc Text: |
A flaw was found in Calibre, an e-book manager. This path traversal vulnerability allows a malicious EPUB (electronic publication) file to corrupt arbitrary files on the system that the Calibre process has write access to. During EPUB conversion, Calibre incorrectly resolves file paths, enabling an attacker to write to locations outside the intended conversion directory. This can lead to significant data integrity issues and potential denial of service.
