Open redirect via excessive scheme-delimiter colons
Published Mar 6, 2022 · Updated Aug 2, 2024
Open redirect in URI.js before 1.19.10 allows remote attackers to redirect users to an attacker-chosen site through a crafted URL. URI.parse() normalizes a web-scheme delimiter only when it contains a single colon; extra colons followed by slashes or backslashes bypass the prior redirect fix. Exploitation requires an application to trust the parsed result and a user to follow or be sent through the resulting redirect, enabling phishing or navigation to an attacker-controlled site.
