Cross-Origin Embedder Policy (COEP) Bypass
Cross-Origin Embedder Policy (COEP) is a security feature implemented by modern web browsers that aims to prevent cross-site scripting attacks. It works by restricting the types of resources that a web page can embed from third-party sources. These restrictions are based on the content type of the resource (e.g. images, scripts, stylesheets).
The purpose of COEP is to prevent malicious scripts from accessing resources that are not intended to be accessed, such as cookies or sensitive user data. However, in certain cases, it is possible to bypass COEP and access these resources by exploiting vulnerabilities in the browser or the web page.
This is known as a COEP bypass, and it can be used by attackers to steal sensitive data or execute malicious code on the user’s device. It is therefore important for web developers and users to be aware of the risks of COEP bypasses and to take appropriate precautions, such as keeping their software up to date and avoiding suspicious websites.
