CVE-2025-54594Network attack vector

Secret theft via privileged canary workflow execution

Published Aug 5, 2025 · Updated Aug 6, 2025

Code injection in Callstack React Native Bottom Tabs 0.9.2 and earlier allows remote attackers to steal repository secrets. The release-canary.yml pull_request_target workflow checks out fork code and runs npm install, executing a pull request's package.json preinstall script with privileged tokens. A fork contributor needs only open a malicious pull request and post !canary; execution can expose GitHub and npm tokens or corrupt future package releases.
