**Name of the Vulnerable Software and Affected Versions** GitHub Enterprise Server versions prior to 3.22 **Description** A time-of-check time-of-use (TOCTOU) race condition—a scenario where a system checks the state of a resource before using it, but the state changes between the check and the use—allows remote code execution. Exploitation requires an authenticated user with write access to a repository and precise timing of concurrent upload requests. **Recommendations** Update to version 3.17.20 Update to version 3.18.14 Update to version 3.19.11 Update to version 3.20.7 Update to version 3.21.5 Update to version 3.22.0

**Name of the Vulnerable Software and Affected Versions** GitHub Enterprise Server versions prior to 3.22 **Description** An incorrect authorization issue allows a user-to-server token scoped to a GitHub App installation to perform write operations on public repositories outside its intended scope. This occurs because the authorization check only verifies if the installation has read permissions on the target repository instead of confirming the token's installation was explicitly granted access. An attacker possessing a victim's user-to-server token could create issues, issue comments, commit comments, and private vulnerability reports on any public repository, appearing as the victim user without indicating app involvement. **Recommendations** Update to version 3.21.2 Update to version 3.20.4 Update to version 3.19.8 Update to version 3.18.11 Update to version 3.17.17 Update to version 3.16.20

**Name of the Vulnerable Software and Affected Versions** GitHub Enterprise Server versions prior to 3.22 **Description** A server-side request forgery (SSRF) issue exists where an unauthenticated attacker can send crafted requests to internal services due to insufficient input validation in an upload endpoint. By injecting path traversal content into request parameters, an attacker can bypass the intended request flow and redirect internal API calls, which may lead to the access of internal services and exposure of sensitive credentials. SSRF is a flaw that allows an attacker to induce the server-side application to make requests to an unintended location. **Recommendations** Update to version 3.16.20 Update to version 3.17.17 Update to version 3.18.11 Update to version 3.19.8 Update to version 3.20.4 Update to version 3.21.1

**Name of the Vulnerable Software and Affected Versions** GitHub Enterprise Server versions prior to 3.21 **Description** An authorization bypass allows an attacker with admin access on one repository to modify the secret scanning push protection delegated bypass reviewer list on another repository. This occurs by manipulating the `owner id` parameter in the request body. While authorization is verified against the repository in the URL, the action is applied to the repository specified in the request body. The impact is limited to assigning existing trusted users as bypass reviewers and does not allow the addition of arbitrary external users. **Recommendations** Update to version 3.14.25 Update to version 3.15.20 Update to version 3.16.16 Update to version 3.17.13 Update to version 3.18.7 Update to version 3.19.4 Update to version 3.20.1

**Name of the Vulnerable Software and Affected Versions** GitHub Enterprise Server versions prior to 3.21 **Description** An improper authorization issue exists where an authenticated attacker can determine the names of private repositories using their numeric ID. This occurs because the mobile upload policy API endpoint ''/mobile/upload policy'' fails to perform an early authorization check, resulting in validation error messages that disclose the full repository name for repositories the caller is not authorized to access. **Recommendations** Update to version 3.20.1 Update to version 3.19.5 Update to version 3.18.8 Update to version 3.17.14 Update to version 3.16.17 Update to version 3.15.21 Update to version 3.14.26

**Name of the Vulnerable Software and Affected Versions** GitHub Enterprise Server versions prior to 3.21 **Description** An incorrect regular expression allows an attacker to bypass OAuth redirect URI validation. An attacker aware of a first-party OAuth application's registered callback URL can create a malicious authorization link. If a victim clicks this link, the OAuth authorization code is redirected to a domain controlled by the attacker, potentially granting unauthorized access to the victim's account based on the scopes granted to the OAuth application. **Recommendations** Update to version 3.20.1 Update to version 3.19.5 Update to version 3.18.8 Update to version 3.17.14 Update to version 3.16.17 Update to version 3.15.21 Update to version 3.14.26

**Name of the Vulnerable Software and Affected Versions** GitHub Enterprise Server versions prior to 3.21 **Description** An improper authorization issue exists in scoped user-to-server (`ghu `) token authorization. An authenticated attacker can access private repositories outside the intended installation scope, potentially performing write operations. This occurs due to an authorization fallback that treats a revoked or deleted installation as a global installation context, which may be combined with token revocation timing and SSH push attribution to obtain and reuse a victim-scoped token. **Recommendations** Update to version 3.20.1, 3.19.5, 3.18.8, 3.17.14, 3.16.17, 3.15.21, or 3.14.26.

**Name of the Vulnerable Software and Affected Versions** GitHub Enterprise Server versions prior to 3.17.11 GitHub Enterprise Server versions prior to 3.18.5 GitHub Enterprise Server versions prior to 3.19.2 **Description** An authorization flaw exists in GitHub Enterprise Server that could allow an attacker to merge a pull request into a repository without necessary push permissions. This is due to an authorization bypass in the `enable auto merge` mutation for pull requests. The issue requires the target repository to allow forking and relies on opening a pull request from a fork controlled by the attacker. Successful exploitation is limited to pull requests with a clean status and branches lacking branch protection rules. **Recommendations** Update GitHub Enterprise Server to version 3.17.11 or later. Update GitHub Enterprise Server to version 3.18.5 or later. Update GitHub Enterprise Server to version 3.19.2 or later.
