{"id":"CVE-2020-15168","aliases":["GHSA-w7rc-rwvf-8q5r"],"url":"https://o3.security/vulnerability/CVE-2020-15168","summary":"The `size` option isn't honored after following a redirect in node-fetch","details":"### Impact\nNode Fetch did not honor the `size` option after following a redirect, which means that when a content size was over the limit, a `FetchError` would never get thrown and the process would end without failure.\n\nFor most people, this fix will have a little or no impact. However, if you are relying on node-fetch to gate files above a size, the impact could be significant, for example: If you don't double-check the size of the data after `fetch()` has completed, your JS thread could get tied up doing work on a large file (DoS) and/or cost you money in computing.\n\n### Patches\nWe released patched versions for both stable and beta channels:\n\n- For `v2`: 2.6.1\n- For `v3`: 3.0.0-beta.9\n\n### Workarounds\nNone, it is strongly recommended to update as soon as possible.\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [node-fetch](https://github.com/node-fetch/node-fetch/issues/new?assignees=&labels=question&template=support-or-usage.md&title=Question%3A+)\n* Contact one of the core maintainers.","published":"2020-09-10T19:15:13.490Z","modified":"2026-10-20T10:51:52.700929648Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},"epss":{"score":0.01692,"percentile":0.75135,"asOf":"2026-08-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"node-fetch","fixedVersion":"2.6.1"},{"ecosystem":"npm","name":"node-fetch","fixedVersion":"3.0.0-beta.9"}],"fix":{"url":"https://github.com/node-fetch/node-fetch/commit/2358a6c2563d1730a0cdaccc197c611949f6a334","label":"node-fetch/node-fetch@2358a6c"},"references":[{"type":"ADVISORY","url":"https://github.com/node-fetch/node-fetch/security/advisories/GHSA-w7rc-rwvf-8q5r"},{"type":"ADVISORY","url":"https://www.npmjs.com/package/node-fetch"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15168"},{"type":"WEB","url":"https://github.com/node-fetch/node-fetch/commit/2358a6c2563d1730a0cdaccc197c611949f6a334"},{"type":"WEB","url":"https://github.com/node-fetch/node-fetch/commit/eaff0094c4dfdd5b78711a8c4f1b61e33d282072"},{"type":"PACKAGE","url":"https://github.com/node-fetch/node-fetch"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-20T10:51:52.700929648Z"}}
