CVE-2026-45287: opentelemetry-go's Schema ParseFile leaks file descriptors on each parse
(updated )
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. The severity is low because exploitation depends on a consuming application exposing repeated schema parsing to an attacker-controlled path.
