CVE-2026-73539
Description
A flaw was found in Gitea. This vulnerability allows an attacker to achieve arbitrary code execution by injecting unintended arguments into external markup rendering commands. When handling markup requests, Gitea fails to sanitize URL reference paths before command argument processing. If an attacker can place a malicious filter file on an accessible path on systems using susceptible renderers, they can execute code with the permissions of the Gitea service account, potentially without prior authentication.
