{"id":"UBUNTU-CVE-2026-39883","details":"OpenTelemetry-Go is the Go implementation of OpenTelemetry. From 1.15.0 to 1.42.0, the fix for CVE-2026-24051 changed the Darwin ioreg command to use an absolute path but left the BSD kenv command using a bare name, allowing the same PATH hijacking attack on BSD and Solaris platforms. This vulnerability is fixed in 1.43.0.","modified":"2026-06-30T18:18:00.078571100Z","published":"2026-04-08T21:17:00Z","upstream":["CVE-2026-39883"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-39883"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-39883"},{"type":"REPORT","url":"https://github.com/open-telemetry/opentelemetry-go/security/advisories/GHSA-hfvc-g4fc-pqhx"},{"type":"REPORT","url":"http://github.com/open-telemetry/opentelemetry-go/releases/tag/v1.43.0"}],"affected":[{"package":{"name":"golang-opentelemetry-otel","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/golang-opentelemetry-otel?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.0-2"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-opentelemetry-otel-dev","binary_version":"1.1.0-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-39883.json"}},{"package":{"name":"golang-opentelemetry-otel","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/golang-opentelemetry-otel?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.16.0-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.16.0-1","binary_name":"golang-opentelemetry-otel-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-39883.json"}},{"package":{"name":"golang-opentelemetry-otel","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/golang-opentelemetry-otel?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.31.0-4"],"ecosystem_specific":{"binaries":[{"binary_version":"1.31.0-4","binary_name":"golang-opentelemetry-otel-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-39883.json"}},{"package":{"name":"golang-opentelemetry-otel","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/golang-opentelemetry-otel?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.31.0-4","1.31.0-5","1.31.0-6"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-opentelemetry-otel-dev","binary_version":"1.31.0-6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-39883.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
