CVE-2023-38745

Pandoc before 3.1.6 allows arbitrary file write: this can be triggered by
providing a crafted image element in the input when generating files via
the --extract-media option or outputting to PDF format. This allows an
attacker to create or overwrite arbitrary files, depending on the
privileges of the process running Pandoc. It only affects systems that pass
untrusted user input to Pandoc and allow Pandoc to be used to produce a PDF
or with the --extract-media option. NOTE: this issue exists because of an
incomplete fix for CVE-2023-35936 (failure to properly account for double
encoded path names).
