| "summary": "Lack of limit when parsing cookies can cause memory exhaustion in net/http", |
| "details": "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.", |
