-## Overview
+# Code Injection in GitHub Actions
+
+## Description
 
 Using user-controlled input in GitHub Actions may lead to code injection in contexts like _run:_ or _script:_.
 
 Code injection in GitHub Actions may allow an attacker to exfiltrate any secrets used in the workflow and the temporary GitHub repository authorization token. The token may have write access to the repository, allowing an attacker to make changes to the repository.
 
-## Recommendation
+## Recommendations
 
 The best practice to avoid code injection vulnerabilities in GitHub workflows is to set the untrusted input value of the expression to an intermediate environment variable and then use the environment variable using the native syntax of the shell/script interpreter (that is, not _${{ env.VAR }}_).
 
 It is also recommended to limit the permissions of any tokens used by a workflow such as the GITHUB_TOKEN.

-## Overview
+# Code Injection in GitHub Actions
+
+## Description
 
 Using user-controlled input in GitHub Actions may lead to code injection in contexts like _run:_ or _script:_.
 
 Code injection in GitHub Actions may allow an attacker to exfiltrate any secrets used in the workflow and the temporary GitHub repository authorization token. The token may have write access to the repository, allowing an attacker to make changes to the repository.
 
-## Recommendation
+## Recommendations
 
 The best practice to avoid code injection vulnerabilities in GitHub workflows is to set the untrusted input value of the expression to an intermediate environment variable and then use the environment variable using the native syntax of the shell/script interpreter (that is, not _${{ env.VAR }}_).
 
 It is also recommended to limit the permissions of any tokens used by a workflow such as the GITHUB_TOKEN.

-## Overview
+# Use of Actions with known vulnerabilities
+
+## Description
 
 The security of the workflow and the repository could be compromised by GitHub Actions workflows that utilize GitHub Actions with known vulnerabilities.
 
-## Recommendation
+## Recommendations
 
 Either remove the component from the workflow or upgrade it to a version that is not vulnerable.

-## Overview
+# Actions Job and Workflow Permissions are not set
+
+## Description
 
 If a GitHub Actions job or workflow has no explicit permissions set, then the repository permissions are used. Repositories created under organizations inherit the organization permissions. The organizations or repositories created before February 2023 have the default permissions set to read-write. Often these permissions do not adhere to the principle of least privilege and can be reduced to read-only, leaving the `write` permission only to a specific types as `issues: write` or `pull-requests: write`.
 
-## Recommendation
+## Recommendations
 
-Add the `permissions` key to the job or the root of workflow (in this case it is applied to all jobs in the workflow that do not have their own `permissions` key) and assign the least privileges required to complete the task.
