{"id":"AZL-111047","summary":"CVE-2026-106069 affecting package nodejs for versions less than 24.22.1-0","details":"A flaw in Node.js TLS hostname verification can cause a server certificate to be validated against a different IP address than the one the client connected to, when the host is a non-canonical IPv4 literal with a leading zero, such as `0127.0.0.1`.\n\n`tls.checkServerIdentity()` normalizes the host following the WHATWG URL rules, which read a leading-zero octet as octal (`0127.0.0.1` becomes `87.0.0.1`), while the connection is made through the operating system resolver, which on some platforms such as macOS reads it as decimal (`127.0.0.1`). A server at the connected address can then be authenticated with a certificate issued for another IP address.\n\nThis vulnerability affects Node.js **26.x**, **24.x**, and **22.x**.","modified":"2026-10-29T05:34:21Z","published":"2026-10-23T17:17:19Z","upstream":["CVE-2026-106069"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-106069"}],"affected":[{"package":{"name":"nodejs","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/nodejs"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"24.22.1-0"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-111047.json"}}],"schema_version":"1.9.2"}
