{"schema":"threatline.record/2","record":{"id":"CVE-2022-51021","aliases":[],"summary":"NotificationX WordPress Plugin < 2.3.12 Unauthenticated SQL Injection via notification REST endpoint","details":"NotificationX plugin for WordPress 2.0.0 before 2.3.12 contains an unauthenticated SQL injection vulnerability that allows remote attackers to manipulate database queries by supplying an array-form 'id' parameter to /wp-json/notificationx/v1/notification/{id}. Attackers can pass id[1] with crafted SQL, such as time-based SLEEP payloads, along with an api_key derived from md5(home_url()), which flows unsanitized into Database::get_where_query to extract database contents. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-18.","categories":["Unclassified"],"product":"NotificationX","vendor":"WPDeveloper","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2022-51021","source_modified_at":"2026-10-23T21:15:37.175Z","fetched_at":"2026-10-23T21:47:51.402276Z","product":"NotificationX","vendor":"WPDeveloper","versions":[{"version":"2.0.0","status":"affected","versionType":"custom","lessThan":"2.3.12"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2022-51021","source_modified_at":"2026-10-23T21:15:37.175Z","fetched_at":"2026-10-23T21:47:51.402276Z","package":{"name":"NotificationX","ecosystem":null},"version":"2.3.12","basis":"first unaffected version stated in the CVE record"}],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00377,"percentile":0.30541,"score_date":"2026-10-23"},"published_at":"2026-10-22T10:57:32.517Z","modified_at":"2026-10-23T21:15:37.175Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2022-51021","fetched_at":"2026-10-23T21:47:51.402276Z","source_modified_at":"2026-10-23T21:15:37.175Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2022-51021","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://wpscan.com/vulnerability/d1480717-726d-4be2-95cb-1007a3f010bb","tags":["third-party-advisory"]},{"source":"CVE List","url":"https://github.com/projectdiscovery/nuclei-templates/blob/main/http/vulnerabilities/wordpress/notificationx-sqli.yaml","tags":["technical-description"]},{"source":"CVE List","url":"https://wordpress.org/plugins/notificationx/","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/notificationx-wordpress-plugin-2.3.12-unauthenticated-sql-injection-via-notification-rest-endpoint","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-23T17:32:53.359523Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-23T21:15:37.175Z","content_hash":"e3367265334a7bd52d2fe15bccf07969ef03dec116c948d985175b0c9ab6d6d2"}}
