Vulnerability details
The vulnerability allows a remote attacker to execute arbitrary code.
The vulnerability exists due to path traversal in the Org-mode renderer when processing Org-mode markup containing a #+INCLUDE directive through the /{owner}/{repo}/markup endpoint. A remote attacker can submit a specially crafted markup request to execute arbitrary code.
Exploitation requires a publicly readable repository accepted by the markup route, and the issue can be chained by reading INTERNAL_TOKEN from app.ini and injecting a Git hook through the internal logger.
