New Amazon WAF CAPTCHA Prompt During Login

[pengpengker]

Describe the bug After submitting a login request via the login function and receiving login_resp, I noticed that it triggered the check_for_cvf mechanism.

Upon inspecting login_resp, I confirmed that this wasn’t the usual simple image CAPTCHA—it was actually AWS WAF. Amazon refers to this as: WAF_ADVERSARIAL_SYNTHETIC_GRID_LEVEL_1, where LEVEL indicates the total number of verification rounds required by the CAPTCHA.

This clearly shows that Amazon has updated their CAPTCHA system. However, when I use the generated oauth_url to log in manually through a browser, everything goes smoothly, and I only encounter a simple graphical CAPTCHA.

Although I’ve implemented logic to handle the WAF_ADVERSARIAL_SYNTHETIC_GRID CAPTCHA, the final submission still gets rejected.

I’m unsure where the error lies—hopefully, I can pinpoint the issue and get a successful submission soon.

I have made a breakthrough in this kind of verification code, but I still need some AI to recognize it. I don’t think I can log in like this easily anymore.
