{"cve":"CVE-2026-100157","nvd":{"published":"2026-10-03T07:16:46.330","modified":"2026-10-06T15:04:52.637","status":"Deferred","description":"The The WP Ultimate Review plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 2.4.3. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. The nonce required to pass the only gate is emitted to unauthenticated visitors via the public review form, and submitted shortcode payloads are auto-published without admin approval by default, meaning exploitation requires no account and no privileged interaction.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","score":6.5},"cwes":["CWE-94"],"references":["https://plugins.trac.wordpress.org/browser/wp-ultimate-review/tags/2.4.3/app/content.php#L217","https://plugins.trac.wordpress.org/browser/wp-ultimate-review/tags/2.4.3/app/content.php#L347","https://plugins.trac.wordpress.org/browser/wp-ultimate-review/tags/2.4.3/app/content.php#L52","https://plugins.trac.wordpress.org/browser/wp-ultimate-review/tags/2.4.3/init.php#L286","https://plugins.trac.wordpress.org/changeset?reponame=&old=3720426%40wp-ultimate-review&new=3720426%40wp-ultimate-review"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-100157","score":0.0028,"percentile":0.20279,"date":"2026-10-25"},"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).
