CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) prevents automated bot attacks. However, if CAPTCHA validation is missing on the server side, attackers can easily bypass it by disabling JavaScript or manipulating client-side code, allowing bots to submit forms without solving the CAPTCHA.
To ensure effective protection, CAPTCHA validation must always occur on the server side after form submission. Relying solely on client-side checks makes it easy for attackers to automate requests or use scripts to bypass restrictions. Proper server-side validation helps verify that the CAPTCHA was genuinely solved by a human before processing any sensitive actions.
Without proper server-side CAPTCHA validation, applications become vulnerable to:
