CVE-2026-45287

A flaw was found in OpenTelemetry-Go (before schema package version 0.0.17). ParseFile in go.opentelemetry.io/otel/schema/v1.0 and v1.1 opens a schema file and passes it to Parse without closing it, leaking one file descriptor per successful call. Repeated parsing in a long-running process can exhaust the file descriptor limit and cause denial of service.

OpenTelemetry-Go schema parsing is vulnerable to file descriptor leak in ParseFile for otel/schema v1.0 and v1.1. An attacker who can cause repeated schema parsing against an attacker-influenced file path in a long-running Go process may exhaust file descriptors and crash or stall the service. Exposure is limited to applications that expose schema parsing to untrusted paths; many Red Hat Go services bundle the library transitively without hitting this code path.
