CVE-2022-43479Public exploitNetwork attack vector

Phishing via unvalidated redirect destination parameters

Published Dec 5, 2022 · Updated Apr 24, 2025

Open redirect in SHIRASAGI 1.14.4 through 1.15.0 allows remote attackers to send users to arbitrary websites through crafted links. The login and schedule endpoints accept an external URL in the ref or calendar[path] parameter and use it as the redirect destination without restricting its origin. No account is required, but a victim must click the crafted SHIRASAGI link; the resulting trust in the original domain can support phishing.
