{"cve":"CVE-2026-113667","nvd":{"published":"2026-10-20T18:17:20.277","modified":"2026-10-21T16:17:24.370","status":"Deferred","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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","score":5.3},"cvss_v3":null,"cwes":["CWE-116"],"references":["https://github.com/apostrophecms/apostrophe/commit/9500b8b0e1d630d5e07fbb5fd2c25ed0943845ce","https://github.com/apostrophecms/apostrophe/commit/f84fd41cbf6c22eb8d0008fc9c25df1f7130b350","https://github.com/apostrophecms/apostrophe/releases/tag/@apostrophecms/form@1.5.5","https://github.com/apostrophecms/apostrophe/security/advisories/GHSA-44qr-rrjg-2cqq"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-113667","score":0.00366,"percentile":0.3014,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-44qr-rrjg-2cqq","url":"https://osv.dev/vulnerability/GHSA-44qr-rrjg-2cqq","summary":"ApostropheCMS: CAPTCHA response token not URL-encoded","modified":"2026-10-20T18:15:04.529028056Z","packages":[{"ecosystem":"npm","name":"@apostrophecms/form","purl":"pkg:npm/%40apostrophecms/form","ranges":["<1.5.5"],"fixed":["1.5.5"]},{"ecosystem":"npm","name":"@apostrophecms/login-recaptcha","purl":"pkg:npm/%40apostrophecms/login-recaptcha","ranges":["<1.2.1"],"fixed":["1.2.1"]},{"ecosystem":"npm","name":"@apostrophecms/login-hcaptcha","purl":"pkg:npm/%40apostrophecms/login-hcaptcha","ranges":["<1.3.0"],"fixed":["1.3.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
