CVE-2026-54314: n8n

High severity, CVSS 7.5. EPSS: 0.5% chance of exploitation in the next 30 days.

n8n is an open source workflow automation platform. Prior to 2.24.0, the Compression node's Decompress operation expanded attacker-controlled archives into memory without enforcing limits on decompressed output size. An unauthenticated attacker could send a small compressed archive to a public webhook workflow using this node, causing the n8n process to terminate due to memory exhaustion and disrupting all workflows in the same instance. This vulnerability is fixed in 2.24.0.

Affected products

• n8n n8n: before 2.24.0 (fixed in 2.24.0)
