Introduction
On 2023-05-01, a security vulnerability was discovered in the Polyfill.io service, which is a popular tool used by many web developers, including those working with the Google Maps Platform. This vulnerability could potentially allow attackers to intercept and modify the scripts being loaded by Polyfill.io, putting the security and functionality of websites and web applications at risk.
What is Polyfill.io?
Polyfill.io is a service that provides a customized set of polyfills – code snippets that add modern JavaScript functionality to older browsers. This is particularly useful for developers who need to support a wide range of browser versions, as it allows them to write code using the latest JavaScript features while ensuring compatibility with older browsers.
The Vulnerability
The security vulnerability in Polyfill.io was discovered by security researchers and was reported to the Polyfill.io team. The vulnerability was caused by the way the Polyfill.io service handled requests for polyfills, which could potentially allow an attacker to intercept and modify the scripts being delivered to the client.
If an attacker were to exploit this vulnerability, they could potentially inject malicious code into the polyfills being loaded by the client, which could then be executed on the user’s browser. This could lead to a wide range of security issues, including data theft, system compromise, and more.
Impact on Google Maps Platform Users
The Google Maps Platform is a popular web mapping service that provides a range of APIs and tools for developers to integrate maps and location-based features into their web applications. Many developers who use the Google Maps Platform also rely on Polyfill.io to ensure their code is compatible with a wide range of browsers.
If a Google Maps Platform user’s website or web application is using Polyfill.io, they could be vulnerable to the security issue described above. This means that the maps and location-based features provided by the Google Maps Platform could potentially be compromised, putting the security and functionality of the user’s website or web application at risk.
Mitigation Strategies
To mitigate the risk posed by the Polyfill.io security vulnerability, Google Maps Platform users should take the following steps:
- Discontinue use of Polyfill.io: As a precautionary measure, Google Maps Platform users should discontinue the use of Polyfill.io and instead use alternative polyfill solutions or implement feature detection and fallbacks directly in their code.
- Update to the latest Google Maps Platform version: Google has released updates to the Google Maps Platform that address the Polyfill.io security vulnerability. Users should ensure they are using the latest version of the Google Maps Platform to benefit from these security improvements.
- Implement additional security measures: Google Maps Platform users should also implement additional security measures, such as regular security audits, content security policies, and other web application security best practices, to further protect their websites and web applications from potential attacks.
For Joomla! users (Joomla 4, Joomla 5 and Joomla 3)
Please remove Google Map API key in case you’re using it, go to Google Cloud and re-generate new project and apply it for your map.
For WordPress users
Do the same way with Joomla!, but you can also can follow Security Report from Wordfence to get latest update for map plugins that you’re using.
Conclusion
The security vulnerability in Polyfill.io poses a significant risk to Google Maps Platform users, as it could potentially allow attackers to compromise the security and functionality of their websites and web applications. By discontinuing the use of Polyfill.io, updating to the latest Google Maps Platform version, and implementing additional security measures, Google Maps Platform users can mitigate this risk and protect their users and their business.
