Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Protection mechanism failure (CVE-ID: CVE-2025-61731)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due CgoPkgConfig allows execution of pkg-config binary with flags that are not explicitly safe-listed. A remote attacker can trick the victim into executing arbitrary commands on the system.


2) 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.
