**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** The user would have to click on a specially crafted URL to be compromised by the attacker.

**What privileges could be gained by an attacker who successfully exploited this vulnerability?** An authenticated attacker would be able to delete targeted files on a system which could result in them gaining SYSTEM privileges.

**Why is this Chrome CVE included in the Security Update Guide?** The vulnerability assigned to this CVE is in Chromium Open Source Software (OSS) which is consumed by Microsoft Edge (Chromium-based). It is being documented in the Security Update Guide to announce that the latest version of Microsoft Edge (Chromium-based) is no longer vulnerable. **How can I see the version of the browser?** 1. In your Microsoft Edge browser, click on the 3 dots (...) on the very right-hand side of the window 2. Click on **Help and Feedback** 3. Click on **About Microsoft Edge**

**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.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** The user would have to click on a specially crafted URL to be compromised by the attacker.

**According to the CVSS metrics, successful exploitation of this vulnerability could lead to minor loss of confidentiality (C:L), integrity (I:L) and availability (A:L). What does that mean for this vulnerability?** While we cannot rule out the impact to Confidentiality, Integrity, and Availability, the ability to exploit this vulnerability by itself is limited. An attacker would need to combine this with other vulnerabilities to perform an attack.
