{"cve":"CVE-2026-45287","nvd":{"published":"2026-06-04T16:16:38.690","modified":"2026-07-22T20:10:00.127","status":"Analyzed","description":"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.","cvss_v4":{"vector":"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","score":2.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-772","CWE-775"],"references":["https://github.com/open-telemetry/opentelemetry-go/commit/e72a235518cb773137efd80336a179028bc34684","https://github.com/open-telemetry/opentelemetry-go/commit/f12d198f161b61735d65705248715aa97021ba8d","https://github.com/open-telemetry/opentelemetry-go/security/advisories/GHSA-995v-fvrw-c78m","https://github.com/open-telemetry/opentelemetry-go/security/advisories/GHSA-995v-fvrw-c78m"],"products":["opentelemetry:telemetry_schema_files"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-45287","score":0.00168,"percentile":0.06028,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-995v-fvrw-c78m","url":"https://osv.dev/vulnerability/GHSA-995v-fvrw-c78m","summary":"opentelemetry-go's Schema ParseFile leaks file descriptors on each parse","modified":"2026-07-15T22:00:51.114132588Z","packages":[{"ecosystem":"Go","name":"go.opentelemetry.io/otel/schema/v1.1","purl":"pkg:golang/go.opentelemetry.io/otel/schema/v1.1","ranges":["<0.0.17"],"fixed":["0.0.17"]},{"ecosystem":"Go","name":"go.opentelemetry.io/otel/schema/v1.0","purl":"pkg:golang/go.opentelemetry.io/otel/schema/v1.0","ranges":["<0.0.17"],"fixed":["0.0.17"]},{"ecosystem":"Go","name":"go.opentelemetry.io/otel/schema","purl":"pkg:golang/go.opentelemetry.io/otel/schema","ranges":["<0.0.17"],"fixed":["0.0.17"]}]},{"id":"GO-2026-5281","url":"https://osv.dev/vulnerability/GO-2026-5281","summary":"opentelemetry-go's Schema ParseFile leaks file descriptors on each parse in go.opentelemetry.io/otel/schema","modified":"2026-06-25T19:45:23.220359827Z","packages":[{"ecosystem":"Go","name":"go.opentelemetry.io/otel/schema","purl":"pkg:golang/go.opentelemetry.io/otel/schema","ranges":["<0.0.17"],"fixed":["0.0.17"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
