GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

CVE-2025-58186 (GCVE-0-2025-58186)

Vulnerability from cvelistv5 – Published: 2025-10-29 22:10 – Updated: 2025-11-04 21:13

Title
Lack of limit when parsing cookies can cause memory exhaustion in net/http
Summary
Despite HTTP headers having a default limit of 1MB, the number of cookies that can be parsed does not have a limit. By sending a lot of very small cookies such as "a=;", an attacker can make an HTTP server allocate a large amount of structs, causing large memory consumption.
