When an authenticated user adds an area to a map entry, the name parameter is stored and later rendered in the map list without HTML sanitization. An attacker can inject malicious script into the area name, which is then executed in the browser context of users who view or interact with the affected map entry, potentially enabling session compromise and unauthorized actions as the victim.","published_at":"2025-12-05T17:16:37.195000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":5.1,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","cvss_v4_severity":"MEDIUM","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-79"],"nvd_references":["https://advcloudfiles.advantech.com/cms/2ca1b071-fd78-4d7f-8a2a-7b4537a95d19/Security%20Advisory%20PDF%20File/SECURITY-ADVISORY----DeviceOn-20251208-2.pdf","https://docs.deviceon.advantech.com/docs/resource/","https://www.vulncheck.com/advisories/advantech-wise-deviceon-server-authenticated-stored-xss-via-devicemap-plan"],"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":"2026-06-28T23:26:31.310434Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"P","value_label":"Passive"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"L","value_label":"Low"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"L","value_label":"Low"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"N","value_label":"None"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"L","value_label":"Low"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"L","value_label":"Low"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"advantech-co.-ltd.","vendor_name":"Advantech Co., Ltd.","product_slug":"wise-deviceon-server","product_name":"WISE-DeviceOn Server","version_start":"0","version_start_inclusive":true,"version_end":"5.4","version_end_inclusive":false,"cpe23_uri":"cve5:advantech-co.-ltd.:wise-deviceon-server:0:5.4"}],"exploit_refs":[],"news":[],"references":[{"url":"https://advcloudfiles.advantech.com/cms/2ca1b071-fd78-4d7f-8a2a-7b4537a95d19/Security%20Advisory%20PDF%20File/SECURITY-ADVISORY----DeviceOn-20251208-2.pdf","source_type":"MISC","tags":[]},{"url":"https://docs.deviceon.advantech.com/docs/resource/","source_type":"MISC","tags":[]},{"url":"https://www.vulncheck.com/advisories/advantech-wise-deviceon-server-authenticated-stored-xss-via-devicemap-plan","source_type":"VENDOR_ADVISORY","tags":["advisory"]}],"timeline":[{"type":"published","at":"2025-12-05T17:16:37.195000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:45:12.189729Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:45:12.189729Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:45:12.189729Z","label":"CVSS score revised","source":"cvelistv5"}]}
