Received Received - Intake
Remote Code Execution in Gogs via Git Rebase Command Injection

Publication date: 2026-06-24

Last updated on: 2026-06-24

Assigner: GitHub, Inc.

Description
Gogs is an open source self-hosted Git service. Prior to 0.14.3, Gogs allows authenticated users to achieve Remote Code Execution (RCE) on the server by creating a pull request with a specially crafted branch name that injects the --exec flag into the git rebase command during the "Rebase before merging" merge operation. This vulnerability is fixed in 0.14.3.

Mitigation Strategies

To mitigate this vulnerability, upgrade Gogs to version 0.14.3 or later, where the issue has been fixed.

Executive Summary

This vulnerability exists in Gogs, an open source self-hosted Git service, in versions prior to 0.14.3. Authenticated users can exploit it by creating a pull request with a specially crafted branch name that injects the --exec flag into the git rebase command during the "Rebase before merging" operation. This injection allows the attacker to execute arbitrary code remotely on the server.

Impact Analysis

The vulnerability can lead to Remote Code Execution (RCE) on the server hosting Gogs. This means an attacker with authenticated access can run arbitrary commands on the server, potentially leading to full system compromise, data theft, data loss, or disruption of services.
