{"cve":"CVE-2026-1442","nvd":{"published":"2026-02-27T05:18:18.713","modified":"2026-06-17T10:15:47.863","status":"Analyzed","description":"Since the encryption algorithm used to protect firmware updates is itself encrypted using key material available to an attacker (or anyone paying attention), the firmware updates may be altered by an unauthorized user, and then trusted by a Unitree product, such as the Unitree Go2 and other models. This issue appears to affect all of Unitree’s current offerings as of February 26, 2026, and so should be considered a vulnerability in both the firmware generation and extraction processes. At the time of this release, there is no publicly-documented mechanism to subvert the update process and insert poisoned firmware packages without the equipment owner’s knowledge.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-321"],"references":["http://takeonme.org/gcves/GCVE-1337-2025-00000000000000000000000000000000000000000000000001111111111110101111111111000000000000000000000000000000000000000000000000000000101","https://github.com/Bin4ry/UniTEABag","https://www.linkedin.com/posts/kevin-finisterre-6431069a_in-case-you-want-to-teabag-unitree-robotics-activity-7432984361014091776-zB4D","https://x.com/bin4rydigit/status/2027197985625420242"],"products":["unitree:go1_air_firmware","unitree:go1_pro_firmware","unitree:go2_air_firmware","unitree:go2_edu_plus_firmware","unitree:go2_edu_standard_firmware","unitree:go2_pro_firmware","unitree:go2_x_firmware"],"source":"nvd","synced_at":"2026-10-19T22:24:17.937441719+00:00"},"epss":{"cve":"CVE-2026-1442","score":0.00167,"percentile":0.05966,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
