For example, `--allow-fs-read=/etc/passwd.*` also allows reading `/etc/passwd`. This requires the wildcard grant to sit directly under the root of the permission tree, for example when it is the only grant for that scope. This is a different root cause from CVE-2026-58043.\n\nThis vulnerability affects Node.js **26.x**.","categories":["Runtimes & languages"],"product":"node","vendor":"nodejs","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-106071","source_modified_at":"2026-10-23T16:15:05.791Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"node","vendor":"nodejs","versions":[{"lessThanOrEqual":"26.12.0","status":"affected","version":"26.12.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":3.6,"severity":"Low","kev":{"listed":false},"epss":{"probability":0.0014,"percentile":0.03015,"score_date":"2026-10-24"},"published_at":"2026-10-23T16:15:05.791Z","modified_at":"2026-10-23T16:15:05.791Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-106071","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T16:15:05.791Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-106071","fetched_at":"2026-10-24T18:03:20.872036Z","source_modified_at":"2026-10-24"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://nodejs.org/en/blog/vulnerability/october-2026-security-releases"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"vendor and product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-23T16:15:05.791Z","content_hash":"0e470fc86a5b65eff2423be3dbf022d547d65fa7e9cbdabd210c8d7fe5301ec8"}}
