CVE-2025-65822
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe ESP32 system on a chip (SoC) that powers the Meatmeet Pro was found to have JTAG enabled. By leaving JTAG enabled on an ESP32 in a commercial product an attacker with physical access to the device can connect over this port and reflash the device's firmware with malicious code which will be executed upon running. As a result, the victim will lose access to the functionality of their device and the attack may gain unauthorized access to the victim's Wi-Fi network by re-connecting to the SSID defined in the NVS partition of the device.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe ESP32 SoC in the Meatmeet Pro has its JTAG debugging interface enabled, allowing an attacker with physical access to connect to the device's JTAG pins, reflash firmware with malicious code, and extract Wi-Fi credentials stored in the NVS partition.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify device firmware versionConnect the Meatmeet Pro to its mobile app and navigate to device settings or about section to view the installed firmware version. Alternatively, if you have serial access to the device, check the boot logs for the firmware version string.Affected if The installed firmware version is exactly 1.0.34.4
-
Locate JTAG pins on the ESP32Physically inspect the PCB for the standard ESP32 JTAG pinout (TMS, TCK, TDI, TDO) near the ESP32 chip. These are typically 2.54mm pitch header pins or test points that may be exposed on the PCB.Affected if JTAG pins or test points are physically present and accessible on the device PCB
-
Check ESP32 eFuse JTAG disable bitConnect to the ESP32 via serial bootloader (GPIO0 to ground) and use esptool.py with command 'esptool.py read_efuse' to inspect eFuse settings. Look for the JTAG_DISABLE eFuse bit.Affected if The JTAG_DISABLE eFuse is not burned (value is 0), indicating JTAG remains enabled
A user is affected if their device runs firmware version 1.0.34.4 AND has accessible JTAG pins with JTAG not disabled in eFuse.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataDisable the JTAG interface on the ESP32 by writing the appropriate eFuse (e.g., JTAG_DISABLE) or disabling it via eFuse software configuration during manufacturing, preventing unauthorized physical access to the debug interface.
