This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires pretty permalinks to be enabled, as the exploit chain depends on get_permalink() embedding the stored percent-encoded post_name in the generated URL.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/wordpress-seo/tags/27.6/admin/class-bulk-editor-list-table.php#L898","https://plugins.trac.wordpress.org/browser/wordpress-seo/tags/27.6/admin/class-bulk-editor-list-table.php#L900","https://plugins.trac.wordpress.org/browser/wordpress-seo/tags/28.0/admin/class-bulk-editor-list-table.php#L898","https://plugins.trac.wordpress.org/browser/wordpress-seo/tags/28.0/admin/class-bulk-editor-list-table.php#L900","https://plugins.trac.wordpress.org/changeset/3598937/wordpress-seo/trunk/admin/class-bulk-editor-list-table.php"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:46:40.600842820+00:00"},"epss":{"cve":"CVE-2026-15425","score":0.00349,"percentile":0.28539,"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).
