JSON cannot represent functions, so a caller-supplied `connect` or `tls` option containing a `checkServerIdentity` callback (or a custom connector function) is silently dropped before it reaches the TLS layer. As a result, a TLS peer whose certificate a custom `checkServerIdentity` was written to reject, but which passes Node's default hostname and chain checks, is silently accepted when the request is made through `BalancedPool`. `Client`, `Pool`, `Agent`, and `RoundRobinPool` destructure `connect`/`tls` before the clone and are not affected. Only applications that use `BalancedPool` with a function-valued `connect`/`tls` option (such as a custom `checkServerIdentity` or connector) are affected.\n\n### Patches\n\nUpgrade to `7.29.1` or `8.10.2`. `BalancedPool` now preserves the `connect` and `tls` options outside the JSON clone, so custom TLS verification callbacks are forwarded to each upstream unchanged.\n\n### Workarounds\n\nUse `Client`, `Pool`, or `Agent` instead of `BalancedPool` for connections that rely on a custom `checkServerIdentity` or connector, until upgraded.","state":0,"publishedAt":"2026-09-29T18:17:15+00:00","modifiedAt":"2026-09-29T18:28:14.9150986+00:00","affected":[{"ecosystem":"npm","name":"undici","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"7.24.1"},{"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:H/I:H/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/nodejs/undici/security/advisories/GHSA-w293-vg96-wgc3","https://nvd.nist.gov/vuln/detail/CVE-2026-84961","https://github.com/nodejs/undici/commit/8f5868fbdbc8f1146dfc1bcd1f2d117790141390","https://github.com/nodejs/undici/commit/f690157d728508652fef14673630c71515123e96","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-w293-vg96-wgc3","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-w293-vg96-wgc3","identifiers":["GHSA-w293-vg96-wgc3","CVE-2026-84961"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
