{"id":"DEBIAN-CVE-2026-29181","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vulnerability is fixed in 1.41.0.","modified":"2026-04-10T02:01:33.680624Z","published":"2026-04-07T21:17:16.003Z","withdrawn":"2026-04-10T02:01:33.680624Z","upstream":["CVE-2026-29181"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-29181"}],"affected":[{"package":{"name":"golang-opentelemetry-otel","ecosystem":"Debian:12","purl":"pkg:deb/debian/golang-opentelemetry-otel?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.0-2","1.10.0-1","1.16.0-1","1.16.0-2","1.19.0-0","1.21.0-1","1.21.0-2","1.21.0-3","1.21.0-4","1.31.0-1","1.31.0-2","1.31.0-3","1.31.0-4","1.31.0-5","1.31.0-6"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-29181.json"}},{"package":{"name":"golang-opentelemetry-otel","ecosystem":"Debian:13","purl":"pkg:deb/debian/golang-opentelemetry-otel?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.31.0-4","1.31.0-5","1.31.0-6"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-29181.json"}},{"package":{"name":"golang-opentelemetry-otel","ecosystem":"Debian:14","purl":"pkg:deb/debian/golang-opentelemetry-otel?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.31.0-4","1.31.0-5","1.31.0-6"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-29181.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
