CVE-2023-2449Network attack vector

Account takeover via plaintext password-reset keys

Published Nov 22, 2023 · Updated Apr 8, 2026

Unverified password change in DeluxeThemes UserPro 5.1.1 and earlier allows remote attackers to take over accounts via exposed reset keys. The userpro_process_form function stores a generated userpro_secret_key in plaintext user metadata, then accepts that value to select an account and replace its password. Exploitation requires disclosure of the key through another flaw, such as the documented shortcode chain, and takeover of an administrator account grants site control.
