CVE-2025-61726Network attack vector

Service interruption via unbounded query parameter parsing

Published Jan 28, 2026 · Updated Aug 28, 2026

Unbounded query parsing in Go standard library net/url before 1.24.12 and 1.25.0 through 1.25.5 allows remote attackers to interrupt services. Request.ParseForm passes URL and URL-encoded form pairs to net/url.ParseQuery, which creates map entries without limiting the parameter count. An unauthenticated HTTP request with many distinct pairs can exhaust process memory, causing the application to crash or become unresponsive.
