CVE-2025-61726

A flaw was found in the net/url package in the Go standard library. The package does not enforce a limit on the number of unique query parameters it parses. A Go application using the net/http.Request.ParseForm method will try to process all parameters provided in the request. A specially crafted HTTP request containing a massive number of query parameters will cause the application to consume an excessive amount of memory, eventually causing the application to crash or become unresponsive, resulting in a denial of service.

CVE-2025-61729

A flaw was found in golang. A remote attacker could exploit this vulnerability by providing a specially crafted certificate during the error string construction process within the `HostnameError.Error()` function. This flaw, caused by unbounded string concatenation, leads to excessive resource consumption. Successful exploitation can result in a denial of service (DoS) for the affected system.
