The power consumption of each row-based display cycle depends on the number of illuminated pixels, allowing a partial recovery of display contents. For example, a hardware implant in the USB cable might be able to leverage this behavior to recover confidential secrets such as the PIN and BIP39 mnemonic. Note: BIP39 secrets are not displayed by default on this device. The side channel is relevant only if the attacker has enough control over the device's USB connection to make power-consumption measurements at a time when secret data is displayed. The side channel is not relevant in other circumstances, such as a stolen device that is not currently displaying secret data.","severity":{"version":"3.1","score":4.6,"vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","level":"medium","assessor":"primary","from":"nvd"},"epss":{"day":"2026-11-09","score":0.00389,"percentile":0.33309,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-200","CWE-203"],"published":"2019-11-02T16:25:42Z","modified":"2026-06-17T02:25:16Z","products":[{"vendor":"shiftcrypto","product":"bitbox02"}],"references":[{"url":"https://blog.inhq.net/posts/oled-side-channel-status-summary/","tags":["x_refsource_MISC","x_transferred","Exploit","Third Party Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2019-18673"},{"url":"https://github.com/advisories/GHSA-f7fr-pcf5-8f29"}],"sources":{"cve":[{"id":"CVE-2019-18673","description":"On SHIFT BitBox02 devices, a side channel for the row-based OLED display was found.
