This implementation results in predictable \nsession identifiers and enables session hijacking or shadowing, where \nthe most recent connection displaces the legitimate charging station and\n receives backend commands intended for that station. This vulnerability\n may allow unauthorized users to authenticate as other users or enable a\n malicious actor to cause a denial-of-service condition by overwhelming \nthe backend with valid session requests.","published_at":"2026-02-26T23:08:22.088000Z","last_modified_at":null,"cvss_v3_score":7.3,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","cvss_v3_severity":"HIGH","cvss_v4_score":6.9,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","cvss_v4_severity":"MEDIUM","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-613"],"nvd_references":["https://chargemap.com/en-us/support","https://www.cisa.gov/news-events/ics-advisories/icsa-26-057-05","https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-057-05.json"],"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":"2026-06-28T23:29:26.116204Z"},"effective_severity":"MEDIUM","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":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"L","value_label":"Low"},{"metric":"I","name":"Integrity","value":"L","value_label":"Low"},{"metric":"A","name":"Availability","value":"L","value_label":"Low"}]},"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":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"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":"L","value_label":"Low"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"chargemap","vendor_name":"Chargemap","product_slug":"chargemap.com","product_name":"chargemap.com","version_start":"All versions","version_start_inclusive":true,"version_end":"All versions","version_end_inclusive":true,"cpe23_uri":"cve5:chargemap:chargemap.com:All versions:All versions"}],"exploit_refs":[],"news":[],"references":[{"url":"https://chargemap.com/en-us/support","source_type":"MISC","tags":[]},{"url":"https://www.cisa.gov/news-events/ics-advisories/icsa-26-057-05","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-057-05.json","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-02-26T23:08:22.088000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:52:12.012794Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:12.012794Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:12.012794Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:12.012794Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:12.012794Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:12.012794Z","label":"CVSS score revised","source":"cvelistv5"}]}
