{"id":"CVE-2026-65058","summary":"Trezor Safe improper security check in on-device display","details":"Trezor Safe 3, Safe 5, and Safe 7 firmware contains a confirmation-binding flaw in the Ethereum sign_tx / sign_tx_eip1559 flow. For contract interactions, the device confirms only the initial calldata chunk while the signature commits to the full streamed calldata. An attacker could present calldata to a victim then supply a different tail that changes the signed transaction. Fixed in 70c9b0c.","modified":"2026-08-12T03:51:34.210394290Z","published":"2026-07-21T20:13:00.560Z","database_specific":{"cna_assigner":"cisa-cg","cwe_ids":["CWE-358"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/65xxx/CVE-2026-65058.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"fixed":"70c9b0c"},{"fixed":"70c9b0c"},{"fixed":"70c9b0c"}]}]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/65xxx/CVE-2026-65058.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-65058"},{"type":"ADVISORY","url":"https://raw.githubusercontent.com/cisagov/CSAF/develop/csaf_files/IT/white/2026/va-26-202-02.json"},{"type":"ADVISORY","url":"https://www.cve.org/CVERecord?id=CVE-2026-65058"},{"type":"FIX","url":"https://github.com/trezor/trezor-firmware/commit/70c9b0c07748"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/trezor/trezor-firmware","events":[{"introduced":"0"},{"fixed":"70c9b0c07748"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-65058.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
