This is due to the `usp_get_submitted_category()` function accepting user-submitted category IDs from the POST body without validating them against the admin-configured allowed categories stored in `usp_options['categories']`. This makes it possible for unauthenticated attackers to assign submitted posts to arbitrary categories, including restricted ones, by crafting a direct POST request with manipulated `user-submitted-category[]` values, bypassing the frontend category restrictions.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-863"],"references":["https://plugins.trac.wordpress.org/browser/user-submitted-posts/tags/20260113/user-submitted-posts.php#L1431","https://plugins.trac.wordpress.org/browser/user-submitted-posts/tags/20260113/user-submitted-posts.php#L298","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3463696%40user-submitted-posts%2Ftrunk&old=3456521%40user-submitted-posts%2Ftrunk&sfp_email=&sfph_mail=","https://www.wordfence.com/threat-intel/vulnerabilities/id/02c5e3ad-5cc3-40b1-a15a-10d53383abe6?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:23:35.260773158+00:00"},"epss":{"cve":"CVE-2026-2126","score":0.00392,"percentile":0.33316,"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).
