CrossOriginEmbedderPolicy
CrossOriginEmbedding is a security feature implemented in web browsers to prevent malicious websites from embedding content from other domains without permission. This feature is crucial for maintaining the integrity and security of web content. When a web page attempts to embed content from a different origin (a different domain, protocol, or port), the browser checks the Cross-Origin Resource Sharing (CORS) policy of the target resource. If the target resource allows embedding from the requesting origin, the content is loaded; otherwise, the browser blocks the request to prevent unauthorized access.
CrossOriginEmbedding is particularly relevant for media elements such as images, videos, and audio files. For example,
The implementation of CrossOriginEmbedding helps mitigate risks such as clickjacking, where an attacker embeds a malicious
In summary, CrossOriginEmbedding is a vital security mechanism that controls how web content from different origins
