CVE-2026-124225

FAQ

How could an attacker exploit this vulnerability?

An attacker could convince a victim, or cause a victim-controlled automated process, to invoke Invoke-WebRequest against an attacker-controlled URL. By returning a specially crafted non-2xx HTML response, the attacker could cause Windows PowerShell to parse the response through MSHTML without displaying the security confirmation prompt, which could execute embedded script in the invoking PowerShell process.

According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?

The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally.

For example, when the score indicates that the Attack Vector is Local and User Interaction is Required, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer.
