CVE-2026-77058 boneIO CVE debrief

Who should care

Defenders responsible for boneIO Black devices on internal networks should assess exposure and prioritize updating affected devices to version 1.6.0 or later to prevent potential loss of integrity and availability.

Why it matters

Defenders should care about CVE-2026-77058 because it allows remote attackers to potentially cause loss of integrity and availability on boneIO Black devices on internal networks. Affected deployments require verification, and updating to version 1.6.0 or later is necessary to prevent exploitation.

• Potential loss of device integrity due to unauthorized cross-origin requests
• Potential loss of device availability due to unauthorized cross-origin requests
• Need for verification of affected deployments and inventory checks
• Priority for updating affected devices to version 1.6.0 or later

Technical summary

The boneIO Black device is vulnerable to Cross-Site Request Forgery (CSRF) attacks due to the lack of CSRF tokens and insufficient validation of Origin or Referer headers. This allows a remote attacker to craft a malicious webpage that sends cross-origin requests to the device when visited by a user on the internal network. Affected deployments require verification, and updating to version 1.6.0 or later is necessary to prevent exploitation. Defenders should prioritize verifying exposure of boneIO Black devices on internal networks and ensuring that all affected devices are updated to version 1.6.0 or later.

Defensive priority

Defenders should prioritize verifying exposure of boneIO Black devices on internal networks and ensuring that all affected devices are updated to version 1.6.0 or later.

Recommended defensive actions

• Verify exposure of boneIO Black devices on internal networks
• Ensure all affected devices are updated to version 1.6.0 or later
• Monitor for suspicious cross-origin requests to boneIO Black devices
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and source item provide details on the CSRF vulnerability in boneIO Black, including its impact on device integrity and availability. However, additional information on potential exploitation or affected deployments is limited.
