Exploit for CVE-2026-59774 in Gitea Allows File Disclosure and Command Execution

## Overview An exploit for CVE-2026-59774 has emerged, targeting Gitea's Org-mode markup renderer. This vulnerability allows unauthenticated attackers to access server-side files through INCLUDE directives. The exploit is classified as weaponized, raising the urgency for mitigation. ## Technical Details The vulnerability exists in the repository markup endpoint of Gitea. Attackers can leverage public repositories to read files accessible to the Gitea service account. If sensitive files like app.ini are disclosed, attackers can obtain the INTERNAL_TOKEN. This token can be used to gain further access and execute commands as the Gitea service account by modifying Git hooks. ## Impact The CVSS score for this vulnerability is 9.8, indicating a critical risk. An attacker can exploit this flaw to read sensitive configuration files and potentially execute arbitrary commands. This could lead to a complete compromise of the Gitea service and any associated repositories. ## Mitigation Defenders should take immediate action to mitigate this vulnerability. Restrict access to sensitive files within Gitea. Ensure that the latest version of Gitea is deployed, as updates may contain fixes for this vulnerability. Regularly audit repository permissions and monitor for unusual activity related to Git hooks.
