In general, the fix is to explicitly define a permissions block for the workflow or for the run-linters job so that the automatically provisioned GITHUB_TOKEN only has the minimal required scopes. For a pure lint job that only needs to read the code, contents: read is sufficient.

The best minimal change without altering existing functionality is to add a permissions block at the workflow root (top level, alongside name and on). This will apply to all jobs (currently just run-linters) that don’t override permissions. We should set:

permissions:
  contents: read

This documents that the workflow only needs read access to repo contents and ensures it remains constrained even if repository or organization defaults change later. Concretely, in .github/workflows/linting.yml, insert the permissions block between the name: Lint line and the on: block (around line 2–3). No imports or other definitions are needed.

In general, the fix is to add an explicit permissions block that grants only the minimal scopes required to run the workflow. Since this job just checks out the repository and notifies Sentry, it only needs read access to repository contents.

The best minimal change is to add permissions: contents: read at the job level for sentry-release. This documents the requirement and prevents the job from inheriting broader repository/organization defaults. No changes to steps or secrets handling are needed.

Concretely, in .github/workflows/sentry.yml, under jobs: sentry-release: name: Create Sentry Release, insert a permissions: section such as:

jobs:
  sentry-release:
    name: Create Sentry Release
    permissions:
      contents: read
    runs-on: ubuntu-latest

No additional imports or methods are required, as this is pure workflow configuration.

In general, to fix log injection when logging user input, you should sanitize the input before logging: for plain-text logs, strip or replace newline and carriage-return characters (and often other control characters) so that a single log call cannot be interpreted as multiple separate log lines. It is also helpful to clearly delimit user input in the log message so that its boundaries are unambiguous.

For this specific code, the minimal, behavior-preserving fix is to avoid logging event.body directly and instead log a sanitized version. We can achieve this by converting event.body to a string (in case it is not already), removing \r and \n characters (and optionally other control chars) using String.prototype.replace with a regular expression, and logging the sanitized value. This change should be applied in hub-search-proxy/handler.js at the console.log on line 53. No new external dependencies are needed; we can rely on built-in JavaScript functionality.

Concretely:

• In hub-search-proxy/handler.js, replace the existing console.log(\Received query: ${event.body}`);` with code that:
  • Safely stringifies event.body (e.g., String(event.body)).
  • Removes newline and carriage-return characters with .replace(/[\r\n]/g, '').
  • Logs the sanitized result in the same message template.
    This preserves the logging purpose (seeing the query body) while preventing a malicious user from injecting extra log entries.
