Name of the Vulnerable Software and Affected Versions
calibre versions prior to 9.10.0
Description
A flaw exists where reading metadata from a malicious EPUB, OPF, or PDF file allows the execution of arbitrary Python code. This occurs when a custom column definition containing a
python: template is embedded within calibre:user metadata and subsequently passed unsanitized to the exec() function in the template formatter. This can be triggered through actions such as Add books or Edit books.Recommendations
Update to version 9.10.0.
