CVE-2025-61726: Golang Go

High severity, CVSS 7.5. EPSS: 2.3% chance of exploitation in the next 30 days.

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.

Affected products

• Golang Go: before 1.24.12 (fixed in 1.24.12); from 1.25.0, before 1.25.6 (fixed in 1.25.6)
