{"id":"AZL-84801","summary":"CVE-2026-29181 affecting package ignition-flatcar for versions less than 2.22.0-5","details":"OpenTelemetry-Go is the Go implementation of OpenTelemetry. From 1.36.0 to 1.40.0, multi-value baggage: header extraction parses each header field-value independently and aggregates members across values. This allows an attacker to amplify cpu and allocations by sending many baggage: header lines, even when each individual value is within the 8192-byte per-value parse limit. This vulnerability is fixed in 1.41.0.","modified":"2026-09-03T05:27:10Z","published":"2026-04-07T21:17:16Z","upstream":["CVE-2026-29181"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-29181"}],"affected":[{"package":{"name":"ignition-flatcar","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/ignition-flatcar"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.22.0-5"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-84801.json"}}],"schema_version":"1.9.0"}
