8.5

Descripcion

WeKan before 8.35 contains a server-side request forgery vulnerability in webhook integration URL handling where the url schema field accepts any string without protocol restriction or destination validation. Attackers who can create or modify integrations can set webhook URLs to internal network addresses, causing the server to issue HTTP POST requests to attacker-controlled internal targets with full board event payloads, and can additionally exploit response handling to overwrite arbitrary comment text without authorization checks.
