Weaponized Exploit for Gitea CVE-2026-59774 Allows Unauthorized File Access

## Overview A weaponized exploit for CVE-2026-59774 has surfaced, targeting the Gitea platform. This vulnerability allows unauthenticated attackers to access sensitive files through the Org-mode markup renderer. The exploit leverages INCLUDE directives to read server-side files that the Gitea service account can access. ## Technical Details The vulnerability exists in the way Gitea processes INCLUDE directives from the repository markup endpoint. Attackers can exploit this flaw by submitting crafted requests to a public repository. If the attacker can read files like `app.ini`, which may contain the `INTERNAL_TOKEN`, they can escalate their attack. This token can be used in conjunction with internal logger access to modify Git hooks, enabling command execution as the Gitea service account. ## Impact The CVSS score for this vulnerability is 9.8, indicating a critical risk. Successful exploitation allows attackers to gain unauthorized access to sensitive files. This can lead to further compromises, including the ability to execute arbitrary commands on the server. Organizations using Gitea should be particularly vigilant, as the potential for data exposure and service disruption is high. ## Mitigation Defenders should take immediate action to mitigate this vulnerability. Restrict access to public repositories to limit exposure. Additionally, review and secure sensitive files that may be accessible through the Gitea service account. Regularly audit file permissions and monitor logs for unusual access patterns. Implementing these measures can help prevent unauthorized access and potential exploitation.
