Published Jun 30, 2026 · Updated Jun 30, 2026

Open redirect in Invoice Ninja through 5.13.26 allows remote attackers to redirect authenticated victims after client portal login. ContactLoginController stores the intended query value without host validation and passes it verbatim to a bare redirect after authentication. Exploitation requires a victim to follow the crafted login link and complete a legitimate login, after which an attacker-controlled site can support phishing.
