[gitea.dev] Gitea: Remote Code Execution via diffpatch Git Hook Installation

Github Advisory Database (Go) · 08 Sep 2026

Summary Gitea's diffpatch endpoint can be abused to install and execute a Git hook from repository-controlled content. An attacker with ordinary write access to a repository can execute arbitrary shell commands as the Gitea OS user. With default open registration, an unauthenticated visitor can obtain the required write access by registering an account and creating a repository. Details services/repository/files/patch.go applies attacker-controlled patches in a shared bare temporary clone: cmdApply := gitcmd.NewCommand("apply", "--index", "--recount", "--cached", "--binary") if...
