CVE-2026-61901Network attack vector

Phishing via post-validation URL decoding

Published Jul 20, 2026 · Updated Jul 20, 2026

Open redirect in HikaShop 6.5.1 and earlier allows remote attackers to send users to external sites through crafted currency-switcher links. The front-end and back-end currency controllers validate the encoded return URL, then decode it for the redirect, so a doubly encoded external address bypasses the safety check. Exploitation requires a user to follow the crafted link and change currency; the flaw enables phishing but does not itself disclose shop data.
