What is CVE-2026-77053?
CVE-2026-77053 is a high-severity vulnerability in boneIO, published on 26 Oct 2026.
Official description
boneIO Black firmware ships with authentication disabled by default. Its management web API listens on all network interfaces and exposes all endpoints without requiring credentials. An unauthenticated remote attacker can fully control the device, causing denial of service, modifying configuration, and operating connected physical circuits. This issue was fixed in version 1.6.0: a device without an administrator account refuses API requests until the owner creates one in the first-run wizard, and every API route is restricted to an authenticated role.
Versions before 1.2.0 are based on Debian 10, are no longer supported and cannot be upgraded in place; affected devices should be re-flashed with the 1.6.0 system image.
Weakness: CWE-306
