When looking at the Chrome Web Store, you may wonder why there are 2 extensions with the exact same icon and name available. From Github, it seems that the original extension by Saba (https://github.com/Lor-Saba/Code-Injector) was updated with a few minor fixes by Urmil Parikh (https://github.com/urmilparikh/Code-Injector/commits), and then re-released. I wish these authors could collaborate on keeping just one version in the store. This situation is confusing, and you could reasonably suspect that one version may be a copy with added malware, even though it is not the case, especially given the extension's broad permissions.

Extension safety

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Code Injector requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • Critical ****** ****** ** ******* ***** ***** *** ** **** ** ***** **** ******** ****** *** ******** ********** * ******* ********
  • High ****** ********* ** * ****** ******** ******** ********** * ******* ******* *****
Risk likelihood
Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension.

Code Injector is very likely to contain malware and should not be trusted. Avoid installing.
