fast-uri: fast-uri: Host confusion via unbalanced URI brackets can bypass security policies
A flaw was found in fast-uri. The library incorrectly processes Uniform Resource Identifier URI hosts containing unbalanced brackets, leading to a discrepancy in how the host is parsed by fast-uri compared to other HTTP clients. This host confusion can allow an attacker to bypass security policie...
fast-uri: fast-uri: Host confusion via skipped IDN canonicalization
A flaw was found in fast-uri, a URI parser for Node.js. This vulnerability arises because the parser fails to consistently convert internationalized domain names IDN to their standard ASCII form when processing scheme-relative references. This inconsistency can lead to host confusion, where an...
