Description

WordPress Plugin Flexible Captcha is prone to multiple vulnerabilities, including arbitrary file upload and cross-site request forgery vulnerabilities. A successful exploit may allow an attacker to upload arbitrary code and run it in the context of the webserver process, which may facilitate unauthorized access or privilege escalation, or to perform certain administrative actions; other attacks are also possible. WordPress Plugin Flexible Captcha version 3.3 is vulnerable; prior versions may also be affected.

Remediation

Update to plugin version 3.4 or latest
