CVE-2026-54687 DangerBlack CVE debrief

Who should care

Defenders responsible for n8n deployments using the n8n-nodes-sqlite3 node should assess exposure and prioritize verification and remediation. They should review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. Defenders should also plan vendor-supported updates or mitigations through normal change control where exposure is confirmed, and check relevant monitoring, detection, and logs for exposed that

Why it matters

CVE-2026-54687 allows remote attackers to potentially read, create, or overwrite files accessible to the n8n process. Defenders should prioritize verification and remediation.

• Verify and update n8n-node-sqlite3 to version 1.0.0 or later to prevent potential file access
• Restrict untrusted input to db_path to prevent unauthorized file selection
• Monitor for suspicious activity related to n8n-nodes-sqlite3

Technical summary

The n8n-nodes-sqlite3 node for n8n exposes the SQLite database file path as a node parameter, allowing data expressions from upstream workflow input. This enables a remote attacker to select which SQLite file the n8n process opens, potentially reading, creating, or overwriting files accessible to the process. The issue is fixed in version 1.0.0. Defenders should prioritize verifying and updating n8n-node-sqlite3 to version 1.0.0 or later, and restrict untrusted input to db_path to prevent unauthorized file selection.

Defensive priority

Defenders should prioritize verifying and updating n8n-node-sqlite3 to version 1.0.0 or later, and restrict untrusted input to db_path.

Recommended defensive actions

• Verify and update n8n-node-sqlite3 to version 1.0.0 or later
• Restrict untrusted input to db_path
• Monitor for suspicious activity
• 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
