CVE-2023-26494Public exploitNetwork attack vector

Phishing via unchecked post-login redirect

Published Apr 24, 2023 · Updated Feb 4, 2025

Open redirect in The Things Stack before 3.24.1 allows remote attackers to send users to an attacker-chosen site after login. The /oauth/login and /oauth/token-login pages take the n query parameter as the post-login destination and assign it to window.location without restricting the destination. Exploitation requires a user to follow a crafted login URL and complete authentication, enabling phishing through a trusted login flow.
