CVE-2023-3404

CWE-321Published: August 31, 2023· Updated: Jun 17, 2026

4.9
CVSS v3.1

Official Description

The ProfileGrid plugin for WordPress is vulnerable to unauthorized decryption of private information in versions up to, and including, 5.5.0. This is due to the passphrase and iv being hardcoded in the 'pm_encrypt_decrypt_pass' function and used across all sites running the plugin. This makes it possible for authenticated attackers, with administrator-level permissions or above to decrypt and view users' passwords. If combined with another vulnerability, this can potentially grant lower-privileged users access to users' passwords.

Technical Analysis

CVE-2023-3404 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), with a CVSS base score of 4.9.
