Phishing via unvalidated redirect URL

Published Dec 24, 2025 · Updated Dec 24, 2025

Open redirect in Jeff Starr User Submitted Posts 20251121 and earlier allows remote attackers to send users to phishing sites. The post-submission redirect path accepts the supplied redirect URL as a destination without validating that it belongs to a trusted site. No authentication is required, but a targeted user must follow a crafted link or perform another attacker-controlled action before the browser leaves the trusted site.
