In RFC6455 section 10.3, it explains why they have made clients mask their outgoing frames (so that a malicious server cannot manipulate a client into sending something in plaintext, as the message could be a HTTP request which could be us… Continue reading Cache poisoning from rfc6455 (WebSockets) not requiring server message to be masked?

Can token decryption endpoint response codes variability lead to security vulnerabilities?

To clarify the question, here’s our case:
We generate encrypted tokens by applying AES-CBC (256 bit) and Base64 to payload:
encrypted_token = Base64.encode(AES_CBC_256.encrypt(key, iv, payload)).
These encrypted tokens are publicly availab… Continue reading Can token decryption endpoint response codes variability lead to security vulnerabilities?
