However, its internal skip-list is built by subtracting the configured methods from the safe-methods set, so an unsafe method (`POST`, `PUT`, `PATCH`, `DELETE`) never lands in the skip-list and is looked up against the cache store. Combined with the storage gate (`canCacheResponse`) having no method check, a heuristically-cacheable response (for example a `404`) with an explicit `Cache-Control: max-age=...` to an unsafe method is stored and replayed on a subsequent identical request. The application's state-changing request never reaches the origin, and undici serves a fabricated response from the cache instead. This occurs with the default configuration (`methods: ['GET']`), which the public API does not allow widening to unsafe methods, so no application misuse is required; an untrusted origin can trigger it purely through its own response headers.\n\n### Patches\n\nUpgrade to `7.29.1` or `8.10.2`. The cache interceptor no longer reads from or writes to the cache for unsafe HTTP methods, while still invalidating existing cache entries on successful unsafe requests.\n\n### Workarounds\n\nNone.","state":0,"publishedAt":"2026-09-29T18:16:28+00:00","modifiedAt":"2026-09-29T18:28:12.5302292+00:00","affected":[{"ecosystem":"npm","name":"undici","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"7.0.0"},{"kind":"fixed","version":"7.29.1"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"undici","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"8.0.0"},{"kind":"fixed","version":"8.10.2"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"LOW"}],"references":["https://github.com/nodejs/undici/security/advisories/GHSA-8436-99hf-9mmv","https://nvd.nist.gov/vuln/detail/CVE-2026-85008","https://github.com/nodejs/undici/commit/2be07bf97b3022e0324142d31f99f6e019d815e3","https://github.com/nodejs/undici/commit/b61d9432bac7caac51273ad209862e4c0bf935ae","https://cna.openjsf.org/security-advisories.html","https://github.com/nodejs/undici","https://github.com/nodejs/undici/releases/tag/v7.29.1","https://github.com/nodejs/undici/releases/tag/v8.10.2"],"sourceUrl":"https://github.com/advisories/GHSA-8436-99hf-9mmv","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-8436-99hf-9mmv","identifiers":["GHSA-8436-99hf-9mmv","CVE-2026-85008"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
