A second STM record named '::$DATA' overwrites the extracted file's default data stream, letting an attacker defeat SmartScreen/MotW warnings and spoof file content.","published_at":"2026-06-28T01:32:54.971000Z","last_modified_at":null,"cvss_v3_score":3.3,"cvss_v3_vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","cvss_v3_severity":"LOW","cvss_v4_score":4.8,"cvss_v4_vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N/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-693"],"nvd_references":["https://github.com/bikini/exploitarium/tree/main/7zip-rar5-motw-chain-poc","https://github.com/ip7z/7zip","https://www.vulncheck.com/advisories/7-zip-mark-of-the-web-bypass-via-rar5-alternate-data-stream-name-collision"],"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":"2026-06-28T17:55:42.709123Z","updated_at":"2026-06-28T23:30:59.112346Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"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":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"L","value_label":"Low"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"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":"P","value_label":"Passive"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"N","value_label":"None"},{"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":"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":"7-zip","vendor_name":"7-Zip","product_slug":"7-zip","product_name":"7-Zip","version_start":"0","version_start_inclusive":true,"version_end":"26.02","version_end_inclusive":true,"cpe23_uri":"cve5:7-zip:7-zip:0:26.02"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/bikini/exploitarium/tree/main/7zip-rar5-motw-chain-poc","source_type":"MISC","tags":[]},{"url":"https://github.com/ip7z/7zip","source_type":"MISC","tags":[]},{"url":"https://www.vulncheck.com/advisories/7-zip-mark-of-the-web-bypass-via-rar5-alternate-data-stream-name-collision","source_type":"VENDOR_ADVISORY","tags":["advisory"]}],"timeline":[{"type":"published","at":"2026-06-28T01:32:54.971000Z","label":"CVE published","source":null}]}
