ApostropheCMS: CAPTCHA response token not URL-encoded

Description

ApostropheCMS is an open-source Node.js content management system. Prior to 1.5.5 of the Form add-on, 1.2.1 of login-recaptcha, and 1.3.0 of login-hcaptcha, these three CAPTCHA integrations interpolate an unencoded user-supplied response token into the provider verification request. Crafted tokens can smuggle request parameters and disrupt CAPTCHA verification and CAPTCHA-gated form or login flows; automated bypass probing is possible, but a successful CAPTCHA bypass or secret disclosure is not established. This issue is fixed in Form 1.5.5, login-recaptcha 1.2.1, and login-hcaptcha 1.3.0.
