This makes it possible for unauthenticated attackers to create new administrator accounts with attacker-supplied credentials via a CSRF-based REST authentication bypass, granted they can trick a site administrator into performing an action such as clicking on a link. This bypass can be combined with WordPress's ?_method=POST method-override support to convert a top-navigation GET request into an authenticated POST to the REST users endpoint, requiring no existing account on the attacker's part.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-352"],"references":["https://plugins.trac.wordpress.org/browser/ai-engine/tags/3.6.2/labs/mcp-oauth.php#L120","https://plugins.trac.wordpress.org/browser/ai-engine/tags/3.6.2/labs/mcp-oauth.php#L121","https://plugins.trac.wordpress.org/browser/ai-engine/tags/3.6.2/labs/mcp-oauth.php#L127","https://plugins.trac.wordpress.org/browser/ai-engine/tags/3.6.2/labs/mcp-oauth.php#L49","https://plugins.trac.wordpress.org/changeset/3628188/ai-engine/trunk/labs/mcp-oauth.php"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:10.050265369+00:00"},"epss":{"cve":"CVE-2026-15988","score":0.00303,"percentile":0.23045,"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).
