Description Summer Long 2021-05-17 23:54:48 UTC

novnc allows open redirection, which could allow phishing attempts.
Risk: By modifying untrusted URL input to a malicious site, an attacker may successfully launch a phishing scam and steal user credentials. Because the server name in the modified link is identical to the original site, phishing attempts could have a more trustworthy appearance.
