CVE-2026-86670Public exploitNetwork attack vector

Credential recovery via unsalted MD5 password hashes

Published Sep 8, 2026 · Updated Sep 8, 2026

Weak password hashing in Aircheng iWebShop 5.0 through 5.15 allows remote attackers to accelerate credential recovery after hash exposure. Password creation, reset, and login paths in controllers/admin.php and related user and seller code store and compare unsalted MD5 digests directly. Exploitation requires prior access to stored hashes; the weakness then enables offline cracking and can expose reusable password-digest cookies.
