site:docs.github.com GitHub Actions permissions {} workflow GITHUB_TOKEN default permissions

💡 Result:

In GitHub Actions, the GITHUB_TOKEN is a unique, short-lived authentication token created for each workflow job [1]. By default, its permissions are determined by settings configured at the repository, organization, or enterprise level [2][3]. Administrators can choose between two default modes: "permissive" (which grants broad read/write access to many scopes) or "restricted" (which grants limited access, typically read-only for contents and none for most other scopes) [3]. You can override these default permissions within your workflow file using the permissions key to implement the principle of least privilege [2][4]. This key can be defined at the top level of a workflow (applying to all jobs) or within individual jobs [2][5]. When using the permissions key: - You can specify access levels for individual scopes (e.g., contents, issues, pull-requests) as read, write, or none [2][5]. - If you specify access for any individual permission, all unspecified permissions are automatically set to none [2][5]. - You can also use the shorthand syntax read-all or write-all to set all permissions at once [5][6]. If a workflow is triggered by a pull request from a forked repository, the GITHUB_TOKEN permissions are automatically downgraded to read-only access for certain scopes to prevent unauthorized access or modification, regardless of your explicit settings, unless the "Send write tokens to workflows from pull requests" setting is enabled [3].

site:github.com/sarisia/actions-status-discord eb045afee445dc055c18d3d90bd0f244fd062708 GITHUB_TOKEN

💡 Result:

The hash eb045afee445dc055c18d3d90bd0f244fd062708 refers to a specific git commit in the GitHub repository sarisia/actions-status-discord [1]. This commit, titled "Automatic build," was authored by the github-actions[bot] on January 9, 2026 [1]. There is no publicly available evidence linking this specific commit hash to a leaked or compromised GITHUB_TOKEN. In the context of GitHub Actions, GITHUB_TOKEN is a temporary, automatically generated token used to authenticate workflows, and it is standard practice to avoid hardcoding or exposing such tokens in commit history. If you are concerned about a potential leak, you should consider the token compromised and revoke it immediately via your repository settings.

Security Misconfiguration (CWE-732): Incorrect Permission Assignment for Critical Resource

이 워크플로우와 고정된 action은 GITHUB_TOKEN을 사용하지 않습니다. 워크플로우 수준에 permissions: {}를 추가하세요. 이를 생략하면 저장소 또는 조직의 기본 권한이 적용될 수 있습니다.
