This makes it possible for authenticated attackers, with custom-level access and above, to read any other user's quiz answers and scores by enumerating the incrementing resultID value via the wpcq_get_quiz_result AJAX action. The only access control on this endpoint is a nonce check (wpc_nonce) that is exposed to every logged-in user on the frontend, providing no meaningful authorization barrier.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-639"],"references":["https://plugins.trac.wordpress.org/browser/wp-courses/tags/3.2.28/classes/WPCQ_Ajax.php#L28","https://plugins.trac.wordpress.org/browser/wp-courses/tags/3.2.28/classes/WPCQ_Ajax.php#L87","https://plugins.trac.wordpress.org/browser/wp-courses/tags/3.2.28/classes/WPCQ_Ajax.php#L91","https://plugins.trac.wordpress.org/browser/wp-courses/tags/3.2.29/classes/WPCQ_Ajax.php#L28","https://plugins.trac.wordpress.org/browser/wp-courses/tags/3.2.29/classes/WPCQ_Ajax.php#L87"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:17.453294893+00:00"},"epss":{"cve":"CVE-2026-10630","score":0.00455,"percentile":0.39237,"date":"2026-10-25"},"kev":null,"osv":[],"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).
