Environment variables cannot be strictly defined in Solr, like Java system properties can be, and may be set for the entire host, unlike Java system properties which are set per-Java-proccess.\n\nThe Solr Metrics API is protected by the \"metrics-read\" permission.\nTherefore, Solr Clouds with Authorization setup will only be vulnerable via users with the \"metrics-read\" permission.\nThis issue affects Apache Solr: from 9.0.0 before 9.3.0.\n\nUsers are recommended to upgrade to version 9.3.0 or later, in which environment variables are not published via the Metrics API.\n\n","published_at":"2024-01-15T09:32:44.532000Z","last_modified_at":null,"cvss_v3_score":6.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":false,"ssvc_technical_impact":"partial","cwes":["CWE-200"],"nvd_references":["https://solr.apache.org/security.html#cve-2023-50290-apache-solr-allows-read-access-to-host-environment-variables"],"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":"2026-06-29T01:41:37.767234Z"},"effective_severity":"MEDIUM","badges":["poc","epss"],"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":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"apache-software-foundation","vendor_name":"Apache Software Foundation","product_slug":"apache-solr","product_name":"Apache Solr","version_start":"9.0.0","version_start_inclusive":true,"version_end":"9.3.0","version_end_inclusive":false,"cpe23_uri":"cve5:apache-software-foundation:apache-solr:9.0.0:9.3.0"}],"exploit_refs":[{"source":"nuclei","kind":"nuclei","url":"https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2023/CVE-2023-50290.yaml","title":"Apache Solr - Host Environment Variables Leak via Metrics API","author":"Banana69,DhiyaneshDK","disclosed_at":null}],"news":[],"references":[{"url":"https://solr.apache.org/security.html#cve-2023-50290-apache-solr-allows-read-access-to-host-environment-variables","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2024-01-15T09:32:44.532000Z","label":"CVE published","source":null},{"type":"poc_available","at":"2026-06-24T00:29:48.638073Z","label":"Public PoC available","source":"nuclei"},{"type":"cvss_changed","at":"2026-06-28T17:30:54.274701Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:30:54.274701Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:30:54.274701Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:41:37.767234Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:41:37.767234Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:41:37.767234Z","label":"SSVC decision revised","source":"vulnrichment"}]}
