This allows authenticated attackers, with subscriber-level permissions and above, to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.","published_at":"2023-07-13T02:04:14.751000Z","last_modified_at":null,"cvss_v3_score":8.8,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":false,"ssvc_technical_impact":"total","cwes":["CWE-502"],"nvd_references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/3590277a-3319-4707-b728-d75ea59e8ad9?source=cve","https://plugins.trac.wordpress.org/browser/user-registration/tags/3.0.1/includes/functions-ur-core.php#L3156","https://plugins.trac.wordpress.org/changeset/2932199/user-registration/trunk/includes/functions-ur-core.php#file0"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-29T01:35:39.862342Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"wpeverest","vendor_name":"wpeverest","product_slug":"user-registration-membership-free-paid-memberships-subscriptions-content-restriction-user-profile-custom-user-registration-login-builder","product_name":"User Registration & Membership – Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder","version_start":"0","version_start_inclusive":true,"version_end":"3.0.1","version_end_inclusive":true,"cpe23_uri":"cve5:wpeverest:user-registration-membership-free-paid-memberships-subscriptions-content-restriction-user-profile-custom-user-registration-login-builder:0:3.0.1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/3590277a-3319-4707-b728-d75ea59e8ad9?source=cve","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/user-registration/tags/3.0.1/includes/functions-ur-core.php#L3156","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset/2932199/user-registration/trunk/includes/functions-ur-core.php#file0","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2023-07-13T02:04:14.751000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:29:32.763511Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:29:32.763511Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:29:32.763511Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:35:39.862342Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:35:39.862342Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:35:39.862342Z","label":"SSVC decision revised","source":"vulnrichment"}]}
