react-native-bottom-tabs is a library of Native Bottom Tabs for React Native. In versions 0.9.2 and below, the github/workflows/release-canary.yml GitHub Actions repository workflow improperly used the pull_request_target event trigger, which allowed for untrusted code from a forked pull request to be executed in a privileged context. An attacker could create a pull request containing a malicious preinstall script in the package.json file and then trigger the vulnerable workflow by posting a specific comment (!canary). This allowed for arbitrary code execution, leading to the exfiltration of sensitive secrets such as GITHUB_TOKEN and NPM_TOKEN, and could have allowed an attacker to push malicious code to the repository or publish compromised packages to the NPM registry. There is a remediation commit which removes github/workflows/release-canary.yml, but a version with this fix has yet to be released.
The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
