This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable via a nonce-free GET request to /wp-admin/profile.php, requiring no profile-form submission; a Subscriber can plant the malicious attachment URL, which then executes when an administrator opens that user's Edit User screen.","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/profile-builder/tags/4.0.2/front-end/default-fields/avatar/avatar.php#L43","https://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.2/front-end/default-fields/avatar/avatar.php#L67","https://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.2/front-end/default-fields/avatar/avatar.php#L75","https://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.2/front-end/default-fields/fields-functions.php#L30","https://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.2/front-end/default-fields/upload/upload_helper_functions.php#L286"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-93656","score":0.00195,"percentile":0.09261,"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).
