Description
This security bulletin contains information about 1 security vulnerability.
1) Input validation error (CVE-ID: CVE-2026-25679)
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.
