CVE-2023-28430 — Onesignal React-Native-Onesignal security vulnerability

High CVSS 8.1

OneSignal is an email, sms, push notification, and in-app message service for mobile apps.The Zapier.yml workflow is triggered on issues (types: [closed]) (i.e., when an Issue is closed). The workflow starts with full write-permissions GitHub repository token since the default workflow permissions on Organization/Repository level are set to read-write. This workflow runs the following step with data controlled by the comment `(${{ github.event.issue.title }} – the full title of the Issue)`, allowing an attacker to take over the GitHub Runner and run custom commands, potentially stealing any secret (if used), or altering the repository. This issue was found with CodeQL using javascript’s Expression injection in Actions query. This issue has been addressed in the repositories github action. No actions are required by users. This issue is also tracked as `GHSL-2023-051`.

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
