CVE-2025-65822 — The ESP32 system on a chip (SoC) that powers the Meatmeet Pro was found to have JTAG…
The 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.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.2% (30-day exploitation probability)+2
- Technical severity (medium)+3
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Meatmeet Meatmeet Pro Wifi & Bluetooth Meat Thermometer Firmware).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes, errors and authentication anomalies.

What should defenders know first?
CVE-2025-65822 is "The ESP32 system on a chip (SoC) that powers the Meatmeet Pro was found to have JTAG…", rated Medium. It affects Meatmeet Pro Wifi & Bluetooth Meat Thermometer Firmware (Meatmeet); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 6.8 describes technical severity. EPSS 0.21% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
