{"id":"BIT-node-min-2026-21716","details":"An incomplete fix for CVE-2024-36137 leaves `FileHandle.chmod()` and `FileHandle.chown()` in the promises API without the required permission checks, while their callback-based equivalents (`fs.fchmod()`, `fs.fchown()`) were correctly patched.\r\n\r\nAs a result, code running under `--permission` with restricted `--allow-fs-write` can still use promise-based `FileHandle` methods to modify file permissions and ownership on already-open file descriptors, bypassing the intended write restrictions.\r\n\r\nThis vulnerability affects **20.x, 22.x, 24.x, and 25.x** processes using the Permission Model where `--allow-fs-write` is intentionally restricted.","aliases":["BIT-node-2026-21716","CVE-2026-21716"],"modified":"2026-04-06T08:41:22.127480989Z","published":"2026-04-06T07:58:58.654Z","database_specific":{"severity":"Low","cpes":["cpe:2.3:a:nodejs:node.js:*:*:*:*:*:*:*:*"]},"references":[{"type":"WEB","url":"https://nodejs.org/en/blog/vulnerability/march-2026-security-releases"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-21716"}],"affected":[{"package":{"name":"node-min","ecosystem":"Bitnami","purl":"pkg:bitnami/node-min"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"20.20.2"},{"introduced":"21.0.0"},{"fixed":"24.14.1"},{"introduced":"25.0.0"},{"fixed":"25.8.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/node-min/BIT-node-min-2026-21716.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"}]}],"schema_version":"1.7.5"}
