In versions 4.0.0 through 6.29.0, 7.0.0 through 7.30.0, and 8.0.0 through 8.12.1, its Agent dispatcher passes its constructor options through a JSON-based deep clone before forwarding them to each per-origin pool, and because JSON cannot represent functions, a caller-supplied tls option containing a checkServerIdentity callback 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. Because Agent is the default dispatcher behind request, fetch, and setGlobalDispatcher, this affects the path most applications use, and EnvHttpProxyAgent is affected on its direct and no-proxy routes as well, while only applications that pass a function-valued tls option such as a custom checkServerIdentity for certificate or public-key pinning are at risk. The issue is fixed in undici 6.29.1, 7.30.1, and 8.12.2, which preserve the tls option outside the JSON clone so custom verification callbacks are forwarded unchanged, and users should upgrade to one of those versions or later. As a workaround, pass the TLS options through connect instead of tls, or for proxied destinations use requestTls and proxyTls.","severity":{"version":"3.1","score":7.4,"vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-12","score":0.00184,"percentile":0.08092,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-295"],"published":"2026-10-15T18:34:01Z","modified":"2026-11-12T00:30:03Z","fixes":[{"ecosystem":"npm","package":"undici","fixed_in":["6.29.1","7.30.1","8.12.2"],"sources":["ghsa","osv"]},{"ecosystem":"Debian:14","package":"node-undici","fixed_in":["8.12.2+dfsg+~cs3.2.3-1"],"sources":["osv"]}],"affected":[{"source":"ghsa","ecosystem":"npm","package":"undici","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"6.29.1"}]}]},{"source":"ghsa","ecosystem":"npm","package":"undici","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.30.1"}]}]},{"source":"ghsa","ecosystem":"npm","package":"undici","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"8.0.0"},{"fixed":"8.12.2"}]}]},{"source":"osv","ecosystem":"AlmaLinux:10","package":"nodejs24","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:24.22.1-3.el10_2"}]}],"bundled":9},{"source":"osv","ecosystem":"AlmaLinux:10","package":"nodejs24-devel","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:24.22.1-3.el10_2"}]}],"bundled":9},{"source":"osv","ecosystem":"AlmaLinux:10","package":"nodejs24-docs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:24.22.1-3.el10_2"}]}],"bundled":9},{"source":"osv","ecosystem":"AlmaLinux:10","package":"nodejs24-full-i18n","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:24.22.1-3.el10_2"}]}],"bundled":9},{"source":"osv","ecosystem":"AlmaLinux:10","package":"nodejs24-libs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:24.22.1-3.el10_2"}]}],"bundled":9},{"source":"osv","ecosystem":"AlmaLinux:10","package":"nodejs24-npm","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:11.19.1-1.24.22.1.3.el10_2"}]}],"bundled":9},{"source":"osv","ecosystem":"AlmaLinux:10","package":"nodejs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:22.23.4-1.el10_2"}]}],"bundled":8},{"source":"osv","ecosystem":"AlmaLinux:10","package":"nodejs-devel","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:22.23.4-1.el10_2"}]}],"bundled":8},{"source":"osv","ecosystem":"AlmaLinux:10","package":"nodejs-docs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:22.23.4-1.el10_2"}]}],"bundled":8},{"source":"osv","ecosystem":"AlmaLinux:10","package":"nodejs-full-i18n","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:22.23.4-1.el10_2"}]}],"bundled":8},{"source":"osv","ecosystem":"AlmaLinux:10","package":"nodejs-libs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:22.23.4-1.el10_2"}]}],"bundled":8},{"source":"osv","ecosystem":"AlmaLinux:10","package":"nodejs-npm","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:10.9.9-1.22.23.4.1.el10_2"}]}],"bundled":8},{"source":"osv","ecosystem":"AlmaLinux:9","package":"nodejs-packaging","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2021.06-6.module_el9.7.0+227+12323393"}]}],"bundled":7},{"source":"osv","ecosystem":"AlmaLinux:9","package":"nodejs-packaging-bundler","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2021.06-6.module_el9.7.0+227+12323393"}]}],"bundled":7},{"source":"osv","ecosystem":"TuxCare:npm","package":"undici","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.11.1-tuxcare.0"},{"fixed":"6.11.1-tuxcare.9"}]}],"versions":["6.11.1","6.11.1-tuxcare.1","6.11.1-tuxcare.2","6.11.1-tuxcare.3","6.11.1-tuxcare.4","6.11.1-tuxcare.5","6.11.1-tuxcare.6","6.11.1-tuxcare.7","6.11.1-tuxcare.8"],"bundled":2},{"source":"osv","ecosystem":"TuxCare:npm","package":"undici","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.28.5-tuxcare.0"},{"fixed":"5.28.5-tuxcare.11"}]}],"versions":["5.28.5","5.28.5-tuxcare.1","5.28.5-tuxcare.10","5.28.5-tuxcare.2","5.28.5-tuxcare.3","5.28.5-tuxcare.4","5.28.5-tuxcare.5","5.28.5-tuxcare.6","5.28.5-tuxcare.7","5.28.5-tuxcare.8","5.28.5-tuxcare.9"],"bundled":2},{"source":"osv","ecosystem":"TuxCare:npm","package":"undici","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.29.0-tuxcare.0"},{"fixed":"7.29.0-tuxcare.5"}]}],"versions":["7.29.0","7.29.0-tuxcare.1","7.29.0-tuxcare.2","7.29.0-tuxcare.3","7.29.0-tuxcare.4"],"bundled":2},{"source":"osv","ecosystem":"TuxCare:npm","package":"undici","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.24.4-tuxcare.0"},{"fixed":"7.24.4-tuxcare.6"}]}],"versions":["7.24.4","7.24.4-tuxcare.1","7.24.4-tuxcare.2","7.24.4-tuxcare.3","7.24.4-tuxcare.4","7.24.4-tuxcare.5"],"bundled":2},{"source":"osv","ecosystem":"TuxCare:npm","package":"undici","ranges":[{"type":"ECOSYSTEM","event

Because `Agent` is the default dispatcher behind `request`, `fetch`, and `setGlobalDispatcher`, this is the path most applications use. `EnvHttpProxyAgent` is also affected on its direct and `NO_PROXY` routes, which delegate to an internal `Agent`.\n\nOnly applications that pass a function-valued `tls` option (such as a custom `checkServerIdentity` for certificate or public-key pinning) are affected.

JSON cannot represent functions, so a caller-supplied `tls` option containing a `checkServerIdentity` callback 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 `Agent`. Because `Agent` is the default dispatcher behind `request`, `fetch`, and `setGlobalDispatcher`, this is the path most applications use. `EnvHttpProxyAgent` is also affected on its direct and `NO_PROXY` routes, which delegate to an internal `Agent`.\n\nOnly applications that pass a function-valued `tls` option (such as a custom `checkServerIdentity` for certificate or public-key pinning) are affected. Passing the same options through `connect` is not affected. This is the `Agent` counterpart of the `BalancedPool` certificate validation bypass fixed in CVE-2026-84961.\n\n### Patches\n\nUpgrade to undici `6.29.1`, `7.30.1`, or `8.12.2`. `Agent` now preserves the `tls` option outside the JSON clone, so custom TLS verification callbacks are forwarded to each origin unchanged.\n\n### Workarounds\n\nPass the TLS options through `connect` instead of `tls`. For proxied `EnvHttpProxyAgent` destinations, use `requestTls` / `proxyTls`.","status":"published","published":"2026-10-27T19:02:26Z","modified":"2026-10-27T19:15:22.40777121Z","cvss":[{"version":"3.1","score":7.4,"vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","level":"high"}],"cwes":["CWE-295"],"updated_at":"2026-11-02T15:46:34.338541Z"},{"id":"RHSA-2026:84657","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs Security Update","status":"published","published":"2026-10-20T10:17:41Z","modified":"2026-10-20T10:43:33.48989051Z","cvss":[{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:23.547034Z"},{"id":"RHSA-2026:84706","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs Security Update","status":"published","published":"2026-10-20T10:17:45Z","modified":"2026-10-20T10:43:36.699091514Z","cvss":[{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:23.547034Z"},{"id":"RLSA-2026:96088","title":"Important: nodejs24 security, bug fix, and enhancement update","description":"Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications.
