CVE-2026-113667 Details
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.
A vulnerability exists in ApostropheCMS versions prior to 1.5.5 of the Form add-on, 1.2.1 of login-recaptcha, and 1.3.0 of login-hcaptcha. These versions of the CAPTCHA integrations fail to properly encode user-supplied response tokens before sending them to the verification server. This oversight allows crafted tokens to inject additional parameters into the verification request, potentially disrupting CAPTCHA validation and bypassing CAPTCHA-restricted forms or login processes. While automated probing for bypassing CAPTCHA is feasible, there is no confirmed exploitation of this issue to successfully bypass CAPTCHA or disclose secrets.
Users can update to ApostropheCMS Form version 1.5.5, login-recaptcha version 1.2.1, or login-hcaptcha version 1.3.0 to address this vulnerability.
