{"id":"CVE-2026-72764","aliases":["GHSA-9cmh-xcqm-5hqr"],"url":"https://o3.security/vulnerability/CVE-2026-72764","summary":"n8n before 1.123.67 Module Cache Poisoning via Code Node","details":"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.","published":"2026-08-11T12:17:05.590Z","modified":"2026-08-13T03:51:33.857284485Z","cvss":null,"epss":{"score":0.00374,"percentile":0.30524,"asOf":"2026-09-07"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"n8n","fixedVersion":"1.123.67"},{"ecosystem":"npm","name":"n8n","fixedVersion":"2.32.1"},{"ecosystem":"npm","name":"n8n","fixedVersion":"2.31.5"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72764.json"},{"type":"ADVISORY","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-9cmh-xcqm-5hqr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72764"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/n8n-before-module-cache-poisoning-via-code-node"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-13T03:51:33.857284485Z"}}
