This is due to the plugin's admin menu being registered at the `edit_posts` capability level — granting Contributor-level users access to the plugin's admin pages and a valid `cg_admin` nonce — while the option-saving handler in `change-options-and-sizes.php` performs no `current_user_can()` capability check beyond `check_admin_referer('cg_admin')`, and the `RegistryUserRole` value is processed only through `sanitize_text_field()` and `htmlentities()` without restriction to an allowlist of permitted role names. This makes it possible for authenticated attackers, with author-level access and above, to overwrite the plugin's stored `RegistryUserRole` option with `administrator`, which the `cg_create_wp_user_from_google_user` function then reads back from the `contest_gal1ery_registry_and_login_options` database table without any allowlist validation and passes directly to `wp_update_user()`, effectively promoting a newly registered Google sign-in account to Administrator."}],"title":"Contest Gallery <= 30.0.2 - Authenticated (Author+) Privilege Escalation via 'RegistryUserRole' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/69b909da-b1b0-4dab-916c-908511f6556f?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/contest-gallery/tags/30.0.2/v10/v10-admin/options/change-options-and-sizes.php#L1242"},{"url":"https://plugins.trac.wordpress.org/browser/contest-gallery/tags/30.0.2/functions/google/cg-create-wp-user-from-google-user.php#L169"},{"url":"https://plugins.trac.wordpress.org/browser/contest-gallery/tags/30.0.2/v10/v10-admin/options/change-options-and-sizes.php#L16"},{"url":"https://plugins.trac.wordpress.org/browser/contest-gallery/tags/30.0.2/index.php#L407"},{"url":"https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3571733%40contest-gallery&new=3571733%40contest-gallery&sfp_email=&sfph_mail="}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-269 Improper Privilege Management","cweId":"CWE-269","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Chloe Chamberland"},{"lang":"en","type":"finder","value":"PRISM"}],"timeline":[{"time":"2026-06-12T19:49:28.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-06-16T20:57:12.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-06-17T10:38:33.394545Z","id":"CVE-2026-12165","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-06-17T10:38:40.424Z"}}]}}
