Is it exploited?

Yes. Previdian sensors observed exploitation attempts with high confidence.

Who is affected?

Gitea affected before 1.27.1.

What should we do?

Patch immediately, validate internet-facing exposure, and monitor for matching requests.

Overview

Gitea Org-mode file disclosure and code execution

Gitea's Org-mode markup renderer processes INCLUDE directives supplied to the repository markup endpoint without preventing access to server-side files. An unauthenticated attacker can use a suitable public repository to read files accessible to the Gitea service account.

If the disclosed files include app.ini and its INTERNAL_TOKEN, the attacker can chain the disclosure with internal logger access to modify a Git hook and execute commands as the Gitea service account.
