Abuse of this behavior could result in the execution of custom code on the server or unauthorized access to application configuration data. This issue affects only the ScreenConnect server component; host and guest clients are not impacted. ScreenConnect 25.8 introduces enhanced server-side configuration handling and integrity checks to ensure only trusted extensions can be installed.","published_at":"2025-12-11T14:21:53.234000Z","last_modified_at":null,"cvss_v3_score":9.1,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","cvss_v3_severity":"CRITICAL","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-494"],"nvd_references":["https://www.connectwise.com/company/trust/security-bulletins/screenconnect-2025.8-security-patch"],"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":"2026-06-28T23:25:24.796813Z"},"effective_severity":"CRITICAL","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":"H","value_label":"High"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"C","value_label":"Changed"},{"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":"connectwise","vendor_name":"ConnectWise","product_slug":"screenconnect","product_name":"ScreenConnect","version_start":"All versions prior to 2025.8","version_start_inclusive":true,"version_end":"All versions prior to 2025.8","version_end_inclusive":true,"cpe23_uri":"cve5:connectwise:screenconnect:All versions prior to 2025.8:All versions prior to 2025.8"}],"exploit_refs":[],"news":[],"references":[{"url":"https://www.connectwise.com/company/trust/security-bulletins/screenconnect-2025.8-security-patch","source_type":"MISC","tags":["patch"]}],"timeline":[{"type":"published","at":"2025-12-11T14:21:53.234000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:41:34.426622Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:41:34.426622Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:41:34.426622Z","label":"CVSS score revised","source":"cvelistv5"}]}
