Debug unlock token cross-device reuse in Caliptra Core ROM and Core Firmware (subsystem mode) allows an attacker who already holds access to an integrator's debug unlock signing service to unlock production debug on an unintended device by presenting a token originally issued for a different device sharing the same debug unlock key hash. The 384-bit challenge nonce prevents replay of previously captured tokens but does not bind a token to a specific target device identity, enabling lateral debug access within a shared-key-hash trust group. No public exploit has been identified and the CVSS 4.0 score of 1.8 reflects the narrow real-world impact, which is bounded by the requirement for high-privilege signing-service access and the hard constraint that exploitation cannot cross key-hash group boundaries.
An SQL injection vulnerability exists in TapHome core HandleMessageUpdateDevicePropertiesRequest function before version 2023.2, allowing low privileged users to inject arbitrary SQL directives into. Rated high severity (CVSS 7.6), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
A hidden API exists in TapHome's core platform before version 2023.2 that allows an authenticated, low privileged user to change passwords of other users without any prior knowledge. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
