{"id":"CVE-2026-63225","aliases":["GHSA-657c-g7qc-r9j2"],"url":"https://o3.security/vulnerability/CVE-2026-63225","summary":"Redocly CLI: Path traversal when using `split` command","details":"Redocly CLI makes OpenAPI validation, linting, and documentation workflows easier. Prior to @redocly/cli 2.33.2, the split command constructs output paths under --outDir from untrusted OpenAPI or AsyncAPI component names and x-codeSamples lang values without verifying that the resolved target remains inside the selected directory. A description containing literal ../ traversal segments in those fields can cause the split command to place or overwrite files outside --outDir. Component data remains constrained to YAML or JSON, and code-sample filenames remain based on the HTTP method, so this is not an unrestricted arbitrary-content file write. This issue is fixed in @redocly/cli version 2.33.2.","published":"2026-09-16T19:09:00.593Z","modified":"2026-09-18T03:48:30.096092438Z","cvss":{"score":4.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L"},"epss":{"score":0.00172,"percentile":0.06871,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@redocly/cli","fixedVersion":"1.34.17"},{"ecosystem":"npm","name":"@redocly/cli","fixedVersion":"2.33.2"}],"fix":{"url":"https://github.com/Redocly/redocly-cli/commit/26a0f299fae0b3bb7bd513043d2f1e90e69f79ee","label":"Redocly/redocly-cli@26a0f29"},"references":[{"type":"WEB","url":"https://github.com/Redocly/redocly-cli/releases/tag/@redocly/cli@1.34.17"},{"type":"WEB","url":"https://github.com/Redocly/redocly-cli/releases/tag/@redocly/cli@2.33.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63225.json"},{"type":"ADVISORY","url":"https://github.com/Redocly/redocly-cli/security/advisories/GHSA-657c-g7qc-r9j2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63225"},{"type":"FIX","url":"https://github.com/Redocly/redocly-cli/commit/26a0f299fae0b3bb7bd513043d2f1e90e69f79ee"},{"type":"FIX","url":"https://github.com/Redocly/redocly-cli/commit/504120419a72b5c684471478337ee3b45d8bfad3"},{"type":"FIX","url":"https://github.com/Redocly/redocly-cli/pull/2891"},{"type":"FIX","url":"https://github.com/Redocly/redocly-cli/pull/2923"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-18T03:48:30.096092438Z"}}
