OESA-2025-2826 (CVE-2025-47912)
Vulnerability from osv_openeuler – Published: 2025-12-12 11:09 – Updated: 2026-08-06 11:09 – Source website.
Security Fix(es):
The Parse function permits values other than IPv6 addresses to be included in square brackets within the host component of a URL. RFC 3986 permits IPv6 addresses to be included within the host component, enclosed within square brackets. For example: "http://[::1]/". IPv4 addresses and hostnames must not appear within square brackets. Parse did not enforce this requirement.(CVE-2025-47912)
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.(CVE-2025-58186)
