Associated Vulnerability

Title: Gitea Org-mode file disclosure and code execution (CVE-2026-59774)
Description: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.

Description

Gitea versions 1.22.1 through 1.27.0 initialize the go-org markup renderer without replacing its default ReadFile callback. An unauthenticated attacker can submit Org-mode markup containing an #+INCLUDE directive with an absolute path to the repository markup endpoint of any public repository, causing the server to read and render arbitrary files accessible to the Gitea service user.
