This vulnerability allows an unauthenticated remote attacker to execute arbitrary OS commands on a victim's computer. The attack vector involves enticing a user to navigate to a malicious webpage, which subsequently leverages the local service interface of the CGServiSign software to inject and execute system-level commands. Given that this interaction occurs through a local service interface exposed to the browser, it presents a significant risk to workstations running the software, as the injected commands inherit the privileges of the service process, likely resulting in full system compromise for the affected host.\u003c/p\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-15027 results in remote code execution on the victim's host.
