Coder from 2.0.0 before 2.34.8 contains an open redirect vulnerability in handleAPIKeySmuggling that allows attackers to redirect users externally via unsanitized r.URL.Path values. Attackers can craft links on trusted workspace app subdomains with paths beginning with double slashes, which become scheme-relative redirects to attacker sites for phishing.
