## CVEs this fix closes

| CVE | Priority | Title | CVSS | EPSS | Exploitation |
|---|---|---|---:|---:|---|
| [CVE-2026-84445](https://patchblox.com/security/data/cve/CVE-2026-84445.md) | High | gRPC-Go: Denial of Service (DoS) via crash due to missing `:authority` and `Host` headers in the xDS servers | 7.5 | 0.0064 |  |
| [CVE-2026-37236](https://patchblox.com/security/data/cve/CVE-2026-37236.md) | High | grpc-gateway v2.28.0 is vulnerable to Incorrect Access Control. The application processes the X-HTTP-Method-Override header in ServeMux.ServeHTTP without restricting allowed methods. When a POST request with Content-Type application/x-www-form-urlencoded includes this header, the request method is rewritten to an arbitrary attacker-supplied value before routing. This allows bypassing method-based access controls enforced by upstream proxies or WAFs. | 9.8 | 0.0043 |  |
| [CVE-2026-41178](https://patchblox.com/security/data/cve/CVE-2026-41178.md) | High | opentelemetry-collector: OpenTelemetry-Go is the Go implementation of OpenTelemetry | 8.2 | 0.0034 |  |
