Name of the Vulnerable Software and Affected Versions TGCaptcha2 version 0.3.0

Description The issue is related to a missing nonce, which enables attackers to reuse a single solved CAPTCHA multiple times, effectively bypassing the CAPTCHA's security mechanism.

Recommendations For TGCaptcha2 version 0.3.0, consider implementing a nonce to prevent replay attacks until a patch is available. As a temporary workaround, restrict the use of the CAPTCHA mechanism to minimize the risk of exploitation.
