{"id":"AZL-81263","summary":"CVE-2026-21715 affecting package nodejs24 for versions less than 24.14.1-1","details":"A flaw in Node.js Permission Model filesystem enforcement leaves `fs.realpathSync.native()` without the required read permission checks, while all comparable filesystem functions correctly enforce them.\r\n\r\nAs a result, code running under `--permission` with restricted `--allow-fs-read` can still use `fs.realpathSync.native()` to check file existence, resolve symlink targets, and enumerate filesystem paths outside of permitted directories.\r\n\r\nThis vulnerability affects **20.x, 22.x, 24.x, and 25.x** processes using the Permission Model where `--allow-fs-read` is intentionally restricted.","modified":"2026-08-28T17:47:55.044327633Z","published":"2026-03-30T20:16:19Z","upstream":["CVE-2026-21715"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-21715"}],"affected":[{"package":{"name":"nodejs24","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/nodejs24"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"24.14.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-81263.json"}}],"schema_version":"1.9.0"}
