🛡️ CVE-2026-45287 on Ubuntu — golang-opentelemetry-otel

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.
