This makes it possible for authenticated attackers, with subscriber-level access and above, to clear or reset any restricted usermeta column for their own user record, including fields marked as \"For admin use only\", bypassing intended field-level access restrictions.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.54/includes/class-forms.php#L2251","https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.54/includes/class-forms.php#L2274","https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.54/includes/class-meta.php#L165","https://plugins.trac.wordpress.org/browser/userswp/trunk/includes/class-forms.php#L2251","https://plugins.trac.wordpress.org/browser/userswp/trunk/includes/class-forms.php#L2274"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-4977","score":0.00297,"percentile":0.2238,"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).
