I have just posted a beta build (v0.94-beta-1) of WordPress Google Forms. This build introduces a new solution for calculating the CAPTCHA. There have been a number of concerns about the use of the PHP eval() function and recently, an alternate solution has been posted to the WordPress Support Forum. I have adapted the proposed solution to the plugin.
This build also addresses a concern about possible security issue with the user-agent string stored when logging submissions. It is technically possible for a malicious user to encode the user agent string with malicious code. This update ensures that data is sanitized before storing and presenting it.Google Forms Beta (1634 downloads)
