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."}],"title":"User Submitted Posts <= 20260113 - Incorrect Authorization to Unauthenticated Category Restriction Bypass via 'user-submitted-category' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/02c5e3ad-5cc3-40b1-a15a-10d53383abe6?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/user-submitted-posts/tags/20260113/user-submitted-posts.php#L298"},{"url":"https://plugins.trac.wordpress.org/browser/user-submitted-posts/tags/20260113/user-submitted-posts.php#L1431"},{"url":"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="}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-863 Incorrect Authorization","cweId":"CWE-863","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","baseScore":5.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"M Indra Purnama"}],"timeline":[{"time":"2026-02-06T18:53:16.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-02-17T20:36:12.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-02-18T12:26:21.098592Z","id":"CVE-2026-2126","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-02-18T12:51:09.152Z"}}]}}
