CVE-2025-61726 — Memory exhaustion in query parameter parsing in net/url

2026-10-04T18:32:53.154853+00:00

Affected: Go standard library net/url, Red Hat Cryostat 4 on RHEL 9, Red Hat HawtIO HawtIO 4.3.1, Red Hat HawtIO HawtIO 4.4.0, Red Hat Ansible Automation Platform 2.4 for RHEL 8, Red Hat Ansible Automation Platform 2.4 for RHEL 9, Red Hat Ansible Automation Platform 2.5 for RHEL 8, Red Hat Ansible Automation Platform 2.5 for RHEL 9, Red Hat Ansible Automation Platform 2.6 for RHEL 10, Red Hat Ansible Automation Platform 2.6 for RHEL 9 and 152 more

The net/url package does not set a limit on the number of query parameters in a query. While the maximum size of query parameters in URLs is generally limited by the maximum request header size, the net/http.Request.ParseForm method can parse large URL-encoded forms. Parsing a large form containing many unique query parameters can cause excessive memory consumption.

GHSA-9h8m-3fm2-qjrq — OpenTelemetry Go SDK Vulnerable to Arbitrary Code Execution via PATH Hijacking

2026-10-04T18:32:53.156915+00:00

Affected: Go: go.opentelemetry.io/otel/sdk

### Impact The OpenTelemetry Go SDK in version `v1.20.0`-`1.39.0` is vulnerable to Path Hijacking (Untrusted Search Paths) on macOS/Darwin systems. The resource detection code in `sdk/resource/host_id.go` executes the `ioreg` system command using a search path. An attacker with the ability to locally modify the PATH environment variable can achieve Arbitrary Code Execution (ACE) within the context of the application.

### Patches This has been patched in [d45961b](https://github.com/open-telemetry/opentelemetry-go/commit/d45961bcda453fcbdb6469c22d6e88a1f9970a53), which was released with `v1.40.0`.
