An attacker that successfully bootstrapped public keys with another entity using PKEX in the past, will be able to subvert a future bootstrapping by passively observing public keys, re-using the encrypting element Qi and subtracting it from the captured message M (X = M - Qi). This will result in the public ephemeral key X; the only element required to subvert the PKEX association.","published_at":"2025-02-11T00:00:00Z","last_modified_at":"2026-07-14T12:16:48.013000Z","cvss_v3_score":6.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/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":true,"ssvc_technical_impact":"partial","cwes":["CWE-323"],"nvd_references":["https://w1.fi/cgit/hostap/commit/?id=15af83cf1846870873a011ed4d714732f01cd2e4","https://link.springer.com/article/10.1007/s10207-025-00988-3"],"vuln_status":"Modified","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":"2026-07-14T15:32:50.783054Z"},"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":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"w1.fi","vendor_name":"w1.fi","product_slug":"hostapd","product_name":"hostapd","version_start":null,"version_start_inclusive":null,"version_end":"2.10","version_end_inclusive":true,"cpe23_uri":"cpe:2.3:a:w1.fi:hostapd:*:*:*:*:*:*:*:*"}],"exploit_refs":[],"news":[],"references":[{"url":"https://w1.fi/cgit/hostap/commit/?id=15af83cf1846870873a011ed4d714732f01cd2e4","source_type":"MISC","tags":["patch"]},{"url":"https://link.springer.com/article/10.1007/s10207-025-00988-3","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2025-02-11T00:00:00Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:23:21.607926Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:23:21.607926Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:23:21.607926Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:12:48.830977Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:12:48.830977Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:12:48.830977Z","label":"SSVC decision revised","source":"vulnrichment"}]}
