| Description | Gitea substitutes a URL derived from the markup Context field into external renderer command templates without escaping the reference path before shell-style argument splitting. A crafted Context can inject additional renderer arguments, including options that load executable filter files. On deployments using a susceptible external renderer such as pandoc, a user who can place a filter file at an accessible path can cause it to execute as the Gitea service account; the public repository markup endpoint itself can be reachable without authentication. | |
