{"id":"UBUNTU-CVE-2026-45287","details":"OpenTelemetry-Go is the Go implementation of OpenTelemetry. Prior to version 0.0.17, `go.opentelemetry.io/otel/schema/v1.0` and `go.opentelemetry.io/otel/schema/v1.1` leaks one file descriptor on each successful `ParseFile` call. `ParseFile` opens the schema file and passes it to `Parse` without closing it; repeated parsing in a long-running process can exhaust the process file descriptor limit and cause denial of service. Exploitation depends on a consuming application exposing repeated schema parsing to an attacker-controlled path. Version 0.0.17 contains a patch for the issue.","modified":"2026-06-23T13:32:06.370561159Z","published":"2026-06-04T16:16:00Z","upstream":["CVE-2026-45287"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-45287"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-45287"},{"type":"REPORT","url":"https://github.com/open-telemetry/opentelemetry-go/security/advisories/GHSA-995v-fvrw-c78m"}],"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_version":"1.1.0-2","binary_name":"golang-opentelemetry-otel-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-45287.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_name":"golang-opentelemetry-otel-dev","binary_version":"1.16.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-45287.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_name":"golang-opentelemetry-otel-dev","binary_version":"1.31.0-4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-45287.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_version":"1.31.0-6","binary_name":"golang-opentelemetry-otel-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-45287.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
