I explain the scenario where Alice locks secrets and grants access to Bob, but when Bob is removed, he loses access to the secrets. However, a malicious peer can exploit this by returning the old authorization list, allowing Bob to access the new secrets. I also demonstrate the code implementation and show how this vulnerability can be exploited. Pay attention to the potential security risks and the importance of maintaining confidentiality.</description></oembed>
