Last modified
CVE-2026-118649 is a high-severity vulnerability rated 8.3/10 on the CVSS scale. n8n before 2.43.5 and 2.44.x before 2.44.1 accepts a client-supplied workflow ID and caches each workflow's owner project in memory by that ID, so a crafted ID such as __proto__ makes the Data Table project check match every project. An authenticated member who can create and run workflows can list, read, modify, and delete Data Table rows in all projects of the instance.. EPSS estimates a 0.27% chance of exploitation in the next 30 days.
