Phishing via unvalidated replyUrl redirects
Published Aug 7, 2026 · Updated Aug 7, 2026
Open redirect in Tobit Laboratories AG TeamDavid Webbox through Rollout 524 allows remote attackers to redirect users via crafted links. The Webbox replyUrl parameter accepts an attacker-controlled destination and places it into a redirect without restricting the target to a trusted host or relative path. Exploitation requires a user to visit the crafted trusted-domain link; the resulting redirect sends the browser to an arbitrary external site and enables phishing.
