Combined with WordPress's permissive REST CORS behavior — which echoes the request `Origin` and sets `Access-Control-Allow-Credentials: true` — this allows an unauthenticated attacker to read REST API GET responses as a logged-in victim, exposing role-restricted and private post/page content, victim user profile data via `/wp-json/wp/v2/users/me`, and comments the victim is authorized to see. This requires the attacker to lure a logged-in user into visiting an attacker-controlled page that issues credentialed cross-origin `fetch` requests against the target site's REST API; no nonce or further victim interaction beyond the page visit is needed.","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:N/A:N","score":6.5},"cwes":["CWE-287"],"references":["https://plugins.trac.wordpress.org/browser/page-and-post-restriction/tags/1.6.0/page-and-post-restriction.php#L54","https://plugins.trac.wordpress.org/browser/page-and-post-restriction/tags/1.6.0/page-and-post-restriction.php#L78","https://plugins.trac.wordpress.org/browser/page-and-post-restriction/tags/1.6.0/page-and-post-restriction.php#L79","https://plugins.trac.wordpress.org/browser/page-and-post-restriction?rev=3771992","https://plugins.trac.wordpress.org/changeset/3771992/page-and-post-restriction/trunk/page-and-post-restriction.php"],"products":[],"source":"nvd","synced_at":"2026-10-30T06:36:07.107513002+00:00"},"epss":null,"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).
