Description

This security bulletin contains information about 1 vulnerability.


1) Input validation error (CVE-ID: CVE-2026-25679)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to bypass URL parsing validation and potentially access unintended resources.

The vulnerability exists due to insufficient validation in net/url.Parse when handling IPv6 literals not located at the start of the host component. A remote attacker can send a specially crafted URL with an IPv6 literal preceded by garbage characters to bypass proper parsing and potentially redirect requests.

This issue affects any application using net/url.Parse to process untrusted URLs. The incorrect parsing may lead to misrouting or injection of unintended host components.
