Closes #109

Live Demo: Available immediately after merge at adrianwedd.github.io/cv via the floating CI/CD button.

The best way to fix this problem is to use a well-tested library for HTML sanitization or tag stripping, such as sanitize-html or striptags. Since the code is only shown in this file and we cannot assume the use of external libraries unless they are well-known, we can use the striptags npm package, which is widely used for removing all HTML tags from a string. This will ensure that all tags, including <script>, are removed, and avoid the pitfalls of incomplete regex-based sanitization. The fix involves:

• Adding an import for striptags at the top of the file.
• Replacing the regex-based HTML tag removal in stripHtml with a call to striptags.
• Ensuring that the rest of the function logic remains unchanged.

To fix the problem, add a permissions block to the continuous-intelligence job, restricting the GITHUB_TOKEN to only the permissions required. In this case, the job only needs to read repository contents, so set permissions: contents: read. This change should be made directly under the continuous-intelligence job definition (after line 41, before timeout-minutes). No additional imports or definitions are needed, as this is a YAML configuration change.

To fix the problem, add an explicit permissions block to the continuous-monitoring job in .github/workflows/continuous-enhancement.yml. Since the job only echoes status and does not interact with the repository or perform any write operations, the most restrictive setting is appropriate. The minimal block is permissions: {} (no permissions), or, for clarity, you can use permissions: read-all if the job needs to read repository metadata. The best fix is to add permissions: {} directly under the name or runs-on key of the continuous-monitoring job (line 445 or 446), ensuring the job does not inherit unnecessary permissions.

---

To fix the problem, add an explicit permissions block to the workflow or to each job that does not already have one. The best practice is to set the minimal permissions required. In this case, the minimal required permission is contents: read, which allows jobs to check out code and read repository contents, but not to write or modify anything. This can be set at the workflow level (applies to all jobs unless overridden), or at the job level for more granularity. Since there is no evidence that any job requires more than read access, the best fix is to add the following at the top level of the workflow (after the name: and before on:):

permissions:
  contents: read

This ensures all jobs in the workflow run with the least privilege required.

---

To fix the problem, add a permissions block to the workflow, either at the root level (to apply to all jobs) or to each job individually. The minimal required permission for these jobs is contents: read, which allows jobs to check out code but not modify repository contents. This should be added near the top of the workflow file, after the name: and before the on: block, or inside each job if different jobs require different permissions. In this case, since all jobs appear to only need read access, adding it at the root level is the best approach. No additional imports or definitions are needed.

To fix the problem, add a permissions block to the dashboard-data-refresh job in .github/workflows/data-refresh-pipeline.yml. This block should specify the minimum required permissions. Since the job only checks out code and does not push changes or interact with issues, the minimal permission required is contents: read. The permissions block should be added directly under the job name (after name: ...) and before runs-on:. No other changes are needed.

---

To fix the problem, add a permissions block to the intelligence-data-refresh job in .github/workflows/data-refresh-pipeline.yml. This block should specify the least privilege required for the job. Since the job does not appear to need write access (it does not commit or push changes), set contents: read as the minimal starting point. This change should be made directly under the job name and before the steps block (after line 382, before line 384). No additional imports or definitions are needed.

To fix the problem, add a permissions block at the top level of the workflow (before jobs:) to restrict the default permissions for all jobs. The minimal recommended setting is contents: read, which allows jobs to read repository contents but not modify them. If any job requires additional permissions (e.g., to write to issues or pull requests), those can be added at the job level. For this workflow, based on the provided code, contents: read is sufficient. The change should be made at the top of .github/workflows/staging-deployment.yml, after the name: and before env: or jobs:.

---

To fix the problem, add an explicit permissions block to the workflow. The best practice is to set the minimal permissions required for each job. For this workflow:

• At the workflow root, set permissions: contents: read to apply to all jobs by default.
• For the staging-build job, which deploys to a branch using peaceiris/actions-gh-pages@v3, override the permissions to contents: write (since deployment requires write access to the repository contents).
• No other jobs appear to require write access, so they can inherit the default read-only permission.

Files/regions to change:

• Add a permissions block at the top level of .github/workflows/staging-deployment.yml (after name: and before on:).
• Add a permissions block under the staging-build job, setting contents: write.

No additional methods, imports, or definitions are needed.

---

To fix the problem, add an explicit permissions block to the workflow. The best practice is to set the most restrictive permissions at the workflow level (e.g., contents: read), and then override with more permissive settings (e.g., contents: write) only for jobs that require them (such as the deployment job). In this workflow, most jobs only need read access, but the staging-build job (which deploys to the gh-pages-staging branch) needs write access to contents. Therefore:

• Add permissions: contents: read at the top level of the workflow (applies to all jobs by default).
• Add permissions: contents: write to the staging-build job, since it pushes to a branch.
• No need to add permissions blocks to the other jobs unless they require more than read access.

This change should be made at the top of the file (after name: and before on:), and within the staging-build job definition.
