The vulnerability exists because the `handle_ajax_save()` function applies per-option safeguards only to names explicitly registered via `register_option_policy()`, causing `get_option_policy()` to return an empty policy — bypassing all can_save, force_mode, and allowed_keys checks — for any unregistered option name, including core WordPress options, while an attacker-controlled `data_name` parameter passes through `sanitize_key()` and is written directly to `update_option()` without restriction. This makes it possible for authenticated attackers with Editor-level access and above to escalate their privileges to Administrator by writing core WordPress options such as `default_role=administrator` and `users_can_register=1`, then self-registering a new Administrator account. The nonce check does not meaningfully restrict this attack, as both the nonce value and nonce action are attacker-supplied POST parameters, and a valid nonce is trivially obtainable via `admin-ajax.php?action=rest-nonce`."}],"title":"Booking Calendar <= 11.8.2 - Authenticated (Editor+) Privilege Escalation to 'data_name' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/ab68a6b2-e9b0-4efa-bd01-c6e3e11011db?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/booking/tags/11.8.2/includes/save-load-option/save-load-option.php#L303"},{"url":"https://plugins.trac.wordpress.org/browser/booking/tags/11.8.2/includes/save-load-option/save-load-option.php#L197"},{"url":"https://plugins.trac.wordpress.org/browser/booking/tags/11.8.2/includes/save-load-option/save-load-option.php#L138"},{"url":"https://plugins.trac.wordpress.org/browser/booking/tags/11.8.2/includes/page-form-builder/ajax/bfb-ajax.php#L82"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3699185%40booking&new=3699185%40booking"}],"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:H/UI:N/S:U/C:H/I:H/A:H","baseScore":7.2,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Wordfence PRISM"}],"timeline":[{"time":"2026-09-16T14:48:37.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-09-17T18:25:01.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-18T17:24:20.308495Z","id":"CVE-2026-92619","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":"2026-09-18T18:32:21.018Z"}}]}}
