Comment 1 Jens Petersen 2025-08-04 09:28:36 UTC

The only thing I can do here is to patch the manpage to explain the potential threat.

The upstream commit related to this just updated the manual
to mention the potential threat of embedding iframe via pdf:
https://github.com/jgm/pandoc/commit/67edf7ce7cd3563a180ae44bd122b012e22364f8
But it is strongly advised not to use pandoc on raw untrusted input.
