{"id":"AZL-92259","summary":"CVE-2026-58253 affecting package telegraf for versions less than 1.31.0-27","details":"NATS Server is a high-performance server for NATS.io, the cloud and edge native messaging system. Prior to 2.14.0, 2.12.7, and 2.11.16, when no_auth_user was configured, a parser fast path intended for ordinary client connections could also apply to route or leafnode listeners, allowing an unauthenticated peer to bypass inter-server CONNECT authentication and operate with the privileges associated with that connection type. This issue is fixed in versions 2.14.0, 2.12.7, and 2.11.16.","modified":"2026-08-31T05:26:27Z","published":"2026-07-08T20:16:54Z","upstream":["CVE-2026-58253"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58253"}],"affected":[{"package":{"name":"telegraf","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/telegraf"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.31.0-27"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-92259.json"}}],"schema_version":"1.9.0"}
