The callback is registered to both wp_ajax_* and wp_ajax_nopriv_* hooks and unconditionally calls delete_option() on four plugin options and delete_transient() on three transients tied to the plugin's API key cache and settings. This makes it possible for unauthenticated attackers to delete plugin options and transients, effectively resetting the plugin's API key/data cache and forcing the plugin to refetch state."}], "title": "Fense Proxy & VPN Blocker <= 3.0.1 - Missing Authorization to Unauthenticated Plugin Option/Transient Deletion via fense_bpvt_save_settings AJAX Action", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/1208ac78-4a56-4daa-b935-d579f07f8e8e?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/fense-block-vpn-proxy/tags/2.9.0/includes/system/fense-bpvt-header-code.php#L32"}, {"url": "https://plugins.trac.wordpress.org/browser/fense-block-vpn-proxy/tags/2.9.0/includes/system/fense-bpvt-header-code.php#L48"}, {"url": "https://plugins.trac.wordpress.org/browser/fense-block-vpn-proxy/tags/3.0.2/includes/system/header-code.php?rev=3574545"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-862 Missing Authorization", "cweId": "CWE-862", "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": "Legion Hunter"}], "timeline": [{"time": "2026-06-15T21:43:06.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-07-16T14:07:41.000Z", "lang": "en", "value": "Disclosed"}]}}}
