{"id":"CVE-2026-72764","state":"PUBLISHED","title":"n8n before 1.123.67 Module Cache Poisoning via Code Node","description":"n8n's JavaScript task runner shared a single module cache across all users' Code-node executions. In affected versions (before 1.123.67, 2.31.5, and 2.32.1), a user able to run a Code node could poison a cached module and thereby alter other users' Code-node executions on the same runner, affecting their confidentiality, integrity, or availability. This is a cross-user isolation break within a single n8n instance and does not constitute a sandbox escape or remote code execution. Only multi-user instances running the JS task runner with built-in or external modules enabled are affected.","publishedAt":"2026-08-11T12:17:05.590Z","updatedAt":"2026-10-29T21:16:37.581Z","severity":{"score":5.8,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H","source":"VulnCheck"},"assigner":"VulnCheck","products":["n8n-io n8n"],"affected":[{"vendor":"n8n-io","product":"n8n","packageURL":"pkg:npm/n8n","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"1.123.67","versionType":"semver"},{"version":"1.123.67","status":"unaffected","versionType":"semver"}]},{"vendor":"n8n-io","product":"n8n","packageURL":"pkg:npm/n8n","defaultStatus":"unaffected","versions":[{"version":"2.32.0","status":"affected","lessThan":"2.32.1","versionType":"semver"},{"version":"2.32.1","status":"unaffected","versionType":"semver"}]},{"vendor":"n8n-io","product":"n8n","packageURL":"pkg:npm/n8n","defaultStatus":"unaffected","versions":[{"version":"2.0.0-rc.0","status":"affected","lessThan":"2.31.5","versionType":"semver"},{"version":"2.31.5","status":"unaffected","versionType":"semver"}]}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-9cmh-xcqm-5hqr","https://www.vulncheck.com/advisories/n8n-before-module-cache-poisoning-via-code-node"],"weaknesses":["CWE-668"],"ingestedAt":"2026-10-29T23:14:04.755Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/72xxx/CVE-2026-72764.json","commit":"dc7676b3f67d6707e4927968546e7e0125ff7ec7","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-72764","state":"PUBLISHED","datePublished":"2026-08-11T12:17:05.590Z","dateUpdated":"2026-10-29T21:16:37.581Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-08-10T15:06:16.417Z"},"containers":{"cna":{"title":"n8n before 1.123.67 Module Cache Poisoning via Code Node","descriptions":[{"lang":"en","value":"n8n's JavaScript task runner shared a single module cache across all users' Code-node executions.
