Technical details

ConvertX through version 0.19.0 invokes Pandoc without the --sandbox flag when converting documents, allowing authenticated users to leverage Pandoc's include directive support in reStructuredText to read arbitrary files. An attacker uploads a reStructuredText file containing an include directive with an absolute path, requests conversion, and retrieves the output containing the referenced file's contents. No fix information is available in the advisory.
