EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.5 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 94% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

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.
