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.","state":0,"publishedAt":"2026-06-23T15:33:52.966+00:00","modifiedAt":"2026-06-24T13:56:50.852+00:00","affected":[{"ecosystem":"Vendor product","name":"n8n","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n8n-io\",\n                    \"product\": \"n8n\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.24.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","score":6.3,"severity":"MEDIUM"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-jqpw-qww5-cj4c"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54314","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54314","identifiers":["CVE-2026-54314"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
