NVD Description

Note: Versions mentioned in the description apply only to the upstream calibre package and not the calibre package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

calibre is a cross-platform e-book manager for viewing, converting, editing, and cataloging e-books. Prior to version 9.6.0, a Server-Side Request Forgery vulnerability in the background-image endpoint of calibre e-book reader's web view allows an attacker to perform blind GET requests to arbitrary URLs and exfiltrate information out from the ebook sandbox. Version 9.6.0 patches the issue.
