CVE-2026-7103Public exploitNetwork attack vector

Password recovery via unsalted MD5 hashing

Published Apr 27, 2026 · Updated Apr 27, 2026

Weak password hashing in Code Projects Chat System 1.0 allows remote attackers to recover passwords from exposed database hashes. The password update path in admin/update_user.php applies unsalted MD5 to each changed password and can retain an unchanged submitted value without rehashing. Exploitation requires access to stored database values; the flaw weakens password protection but does not itself disclose the hashes.
