CVE-2022-46155 : What You Need to Know

Airtable.js credentials exposed in browser builds.

Understanding CVE-2022-46155

This CVE involves a vulnerability in Airtable.js that exposes sensitive credentials in browser builds.

What is CVE-2022-46155?

Airtable.js, the JavaScript client for Airtable, had a misconfigured build script in versions prior to 0.11.6. During the build process, certain environment variables, including AIRTABLE_API_KEY and AIRTABLE_ENDPOINT_URL, could be bundled into the build target of a transpiled bundle.

The Impact of CVE-2022-46155

Users who run the build script locally with specific conditions met could unintentionally expose their Airtable API keys bundled into the local source code. This could lead to unauthorized access to these keys and potential security breaches.

Technical Details of CVE-2022-46155

This section provides more insights into the vulnerability.

Vulnerability Description

The misconfiguration in the build script allowed sensitive environment variables to be included in the transpiled bundle of locally built Airtable.js copies. This could result in the accidental exposure of API keys.

Affected Systems and Versions

The vulnerability impacts Airtable.js versions prior to 0.11.6. Users who perform local builds of the script with specific conditions are affected.

Exploitation Mechanism

By running the

npm prepare

script with the AIRTABLE_API_KEY environment variable set, users unintentionally include their API keys in the built code, making it vulnerable to exposure.

Mitigation and Prevention

To safeguard against this vulnerability, users should take immediate and long-term security measures.

Immediate Steps to Take

Users are advised to upgrade to Airtable.js version 0.11.6 or higher. As a workaround, unset the AIRTABLE_API_KEY environment variable from the shell configurations and regenerate any Airtable API keys.

Long-Term Security Practices

Ensure that sensitive credentials are not bundled in the source code during the build process. Implement secure coding practices to prevent such exposures in the future.

Patching and Updates

Regularly check for updates and security advisories related to Airtable.js. Apply patches promptly and follow best practices to protect sensitive information.
