This is due to the plugin providing user-controlled access to objects, letting a user bypass authorization and access system resources. This makes it possible for authenticated attackers with subscriber-level permissions or above to change user passwords and potentially take over administrator accounts.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-639"],"references":["https://plugins.trac.wordpress.org/browser/simplr-registration-form/trunk/lib/profile.php#L148","https://www.wordfence.com/threat-intel/vulnerabilities/id/6ddf0452-3afe-4ada-bccc-30c818968a81?source=cve","https://plugins.trac.wordpress.org/browser/simplr-registration-form/trunk/lib/profile.php#L148","https://www.wordfence.com/threat-intel/vulnerabilities/id/6ddf0452-3afe-4ada-bccc-30c818968a81?source=cve"],"products":["mikevanwinkle:simplr_registration_form_plus\\+"],"source":"nvd","synced_at":"2026-10-19T21:39:24.235896374+00:00"},"epss":{"cve":"CVE-2023-4213","score":0.00751,"percentile":0.55025,"date":"2026-11-01"},"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).
