Cross-Site Request Forgery and Script Injection Vulnerability in BEAR for WordPress Plugin

CVE-2023-4920 · HIGH Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

The BEAR for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.1.3.3. This is due to missing or incorrect nonce validation on the woobe_save_options function. This makes it possible for unauthenticated attackers to modify the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. Additionally, input sanitization and escaping is insufficient resulting in the possibility of malicious script injection.
