CVE-2025-61726
Last modified
CVE-2025-61726 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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. EPSS estimates a 0.76% chance of exploitation in the next 30 days.
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.
