This is due to a two-step logic flaw: the topic_add() and topic_edit() action handlers accept arbitrary user-supplied data[*] arrays from $_REQUEST and store them as postmeta without restricting which fields may contain array values. Because 'body' is included in the allowed topic fields list, an attacker can supply data[body][fileurl] with an arbitrary file path (e.g., wp-config.php or an absolute server path). This poisoned fileurl is persisted to the plugin's custom postmeta database table. Subsequently, when the attacker submits wpftcf_delete[]=body on a topic_edit request, the add_file() method retrieves the stored postmeta record, extracts the attacker-controlled fileurl, passes it through wpforo_fix_upload_dir() which only rewrites legitimate wpforo upload paths and returns all other paths unchanged, and then calls wp_delete_file() on the unvalidated path. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files writable by the PHP process on the server, including critical files such as wp-config."}],"metrics":{"cvssMetricV31":[{"source":"security@wordfence.com","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:H","baseScore":7.1,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":4.2}]},"weaknesses":[{"source":"security@wordfence.com","type":"Primary","description":[{"lang":"en","value":"CWE-73"}]}],"references":[{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.0.2/classes/Actions.php#L746","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.0.2/classes/Actions.php#L761","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.0.2/classes/PostMeta.php#L402","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.0.2/classes/PostMeta.php#L421","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.0.2/classes/PostMeta.php#L523","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.0.2/classes/Posts.php#L1961","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.0.2/includes/functions.php#L2641","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/changeset/3503313/wpforo","source":"security@wordfence.com"},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/0e46ac8d-89ee-4480-bb96-83f2044a4323?source=cve","source":"security@wordfence.com"}]}}]}
