Title: reCAPTCHA Bypass Vulnerability Using Tesseract OCR

Issue: The current implementation of reCAPTCHA in our project is susceptible to bypass using Tesseract OCR due to the easily readable nature of the generated captchas. This poses a security risk as automated scripts can exploit this weakness, compromising the intended protection.

Recommendation: To enhance security, I propose exploring alternative Python libraries for captcha generation that provide a higher level of complexity and obfuscation. Libraries such as captcha, multicolorcaptcha can be considered to improve the resilience against OCR-based attacks.

Steps to Reproduce:

  1. Utilize Tesseract OCR or Windows / PowerToys to attempt captcha bypass.
  2. Observe the successful recognition of reCAPTCHA images.
  3. Highlight the need for a more robust captcha generation approach.

Expected Behavior: reCAPTCHA should be challenging for OCR tools to decipher, ensuring a higher level of protection against automated attacks.

Additional Information:

Note: Please consider implementing the suggested changes to fortify the security of the captcha system.
