{"id":"CVE-2026-45287","aliases":["GHSA-995v-fvrw-c78m","GO-2026-5281"],"url":"https://o3.security/vulnerability/CVE-2026-45287","summary":"OpenTelemetry-Go's Schema ParseFile leaks file descriptors on each parse","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.","published":"2026-06-04T14:45:54.522Z","modified":"2026-08-12T03:51:09.230033078Z","cvss":null,"epss":{"score":0.00168,"percentile":0.06457,"asOf":"2026-08-15"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"go.opentelemetry.io/otel/schema/v1.1","fixedVersion":"0.0.17"},{"ecosystem":"Go","name":"go.opentelemetry.io/otel/schema/v1.0","fixedVersion":"0.0.17"},{"ecosystem":"Go","name":"go.opentelemetry.io/otel/schema","fixedVersion":"0.0.17"}],"fix":{"url":"https://github.com/open-telemetry/opentelemetry-go/commit/e72a235518cb773137efd80336a179028bc34684","label":"open-telemetry/opentelemetry-go@e72a235"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45287.json"},{"type":"ADVISORY","url":"https://github.com/open-telemetry/opentelemetry-go/security/advisories/GHSA-995v-fvrw-c78m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45287"},{"type":"FIX","url":"https://github.com/open-telemetry/opentelemetry-go/commit/e72a235518cb773137efd80336a179028bc34684"},{"type":"FIX","url":"https://github.com/open-telemetry/opentelemetry-go/commit/f12d198f161b61735d65705248715aa97021ba8d"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:09.230033078Z"}}
