CVE-2026-72762
HighCVSS 7.7Summary
Vulnerability in n8n before versions 1.123.67, 2.31.5, and 2.32.1 allows arbitrary file write 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.
Risk Assessment
The risk includes the ability to write malicious files on the server, potentially leading to system integrity breaches or further attacks.
Recommendation
Upgrade n8n to versions 1.123.67, 2.31.5, or 2.32.1 which contain the fix.
