This allows authenticated attackers, with subscriber-level permissions and above, to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.","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-502"],"references":["https://plugins.trac.wordpress.org/browser/user-registration/tags/3.0.1/includes/functions-ur-core.php#L3156","https://plugins.trac.wordpress.org/changeset/2932199/user-registration/trunk/includes/functions-ur-core.php#file0","https://www.wordfence.com/threat-intel/vulnerabilities/id/3590277a-3319-4707-b728-d75ea59e8ad9?source=cve","https://plugins.trac.wordpress.org/browser/user-registration/tags/3.0.1/includes/functions-ur-core.php#L3156","https://plugins.trac.wordpress.org/changeset/2932199/user-registration/trunk/includes/functions-ur-core.php#file0"],"products":["wpeverest:user_registration"],"source":"nvd","synced_at":"2026-10-19T21:38:35.729974749+00:00"},"epss":{"cve":"CVE-2023-3343","score":0.01126,"percentile":0.66315,"date":"2026-10-31"},"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).
