The `post_edit` action handler in `Actions.php` passes `$_REQUEST['post']` directly to `Posts::edit()`, which calls `extract($args, EXTR_OVERWRITE)`. An attacker can inject `post[guestposting]=1` to overwrite the local `$guestposting` variable, causing the entire permission check block to be skipped. The nonce check uses a hardcoded `wpforo_verify_form` action shared across all 8 forum templates, so any user who can view any forum page obtains a valid nonce. This makes it possible for authenticated attackers, with Subscriber-level access and above, to edit the title, body, name, and email fields of any forum post, including posts in private forums, admin posts, and moderator posts. Content passes through `wpforo_kses()` which strips JavaScript but allows rich HTML."}],"id":"CVE-2026-4666","lastModified":"2026-06-17T10:56:59.773","metrics":{"cvssMetricV31":[{"cvssData":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"NONE","baseScore":6.5,"baseSeverity":"MEDIUM","confidentialityImpact":"NONE","integrityImpact":"HIGH","privilegesRequired":"LOW","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"exploitabilityScore":2.8,"impactScore":3.6,"source":"security@wordfence.com","type":"Secondary"}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"id":"CVE-2026-4666","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","timestamp":"2026-04-17T14:31:11.800069Z","version":"2.0.3"}}]},"published":"2026-04-17T04:16:11.023","references":[{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/2.4.16/classes/Actions.php#L773"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/2.4.16/classes/Posts.php#L283"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/2.4.16/classes/Posts.php#L285"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/2.4.16/includes/functions.php#L532"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/changeset?old_path=%2Fwpforo/tags/2.4.16&new_path=%2Fwpforo/tags/2.4.17"},{"source":"security@wordfence.com","url":"https://ti.wordfence.io/vendors/patch/1885/download"},{"source":"security@wordfence.com","url":"https://wordpress.org/plugins/wpforo/"},{"source":"security@wordfence.com","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/049ffab1-677d-4112-9f1d-092ee01299f1?source=cve"}],"sourceIdentifier":"security@wordfence.com","vulnStatus":"Deferred","weaknesses":[{"description":[{"lang":"en","value":"CWE-862"}],"source":"security@wordfence.com","type":"Secondary"}]}
