Last modified
CVE-2026-72762 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. n8n versions before 1.123.67, 2.31.5, and 2.32.1 contain an arbitrary file write vulnerability in the Edit Image node, which passes its output format parameter to the underlying image library without validation. An authenticated user able to run workflows can supply a crafted format value to write arbitrary files outside the node's working directory on the n8n instance.. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
