## What is CVE-2023-2449?

CVE-2023-2449 is a critical authentication bypass vulnerability in UserPro - Community and User Profile WordPress Plugin, published on 22 Nov 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The UserPro plugin for WordPress is vulnerable to unauthorized password resets in versions up to, and including 5.1.1. This is due to the plugin using native password reset functionality, with insufficient validation on the password reset function (userpro_process_form). The function uses the plaintext value of a password reset key instead of a hashed value which means it can easily be retrieved and subsequently used. An attacker can leverage CVE-2023-2448 and CVE-2023-2446, or another vulnerability like SQL Injection in another plugin or theme installed on the site to successfully exploit this vulnerability.

Weakness: CWE-620 (Unverified Password Change)
