CVE-2025-61726
Memory exhaustion in query parameter parsing in net/url
7.5
HIGH
CVSS 3.1
EPSS 0.04%
Description
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.
