CVE-2026-54313: n8n

High severity, CVSS 7.7. EPSS: 0.3% chance of exploitation in the next 30 days.

n8n is an open source workflow automation platform. Prior to 2.24.0, an authenticated user with workflow edit access could supply a malicious filter value in the MongoDB node's Find And Replace operation. The value was not validated before being passed to MongoDB as a query filter, allowing unintended documents to be matched and overwritten with attacker-controlled content. This vulnerability is fixed in 2.24.0.
