**According to the CVSS score, the attack vector is Local. 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.

**How could an attacker exploit this vulnerability?** An attacker could send a specially crafted request to a vulnerable Dynamics site and overwrite database contents.

**The CVSS Score says user action is required. What type of user action is required?** An authenticated user would have to visit a specific URL that will create an action for a workflow.

**What actions do I need to take to be protected from this vulnerability?** The main update will be automatically pushed to all affected products and services.

The package can be downloaded from NPM or NuGet Gallery. **How do I know if I am affected?** Our team will contact customers that are affected by this vulnerability. We recommend that affected customers save their Power Apps to ensure the fix takes effect as expected.

**Is the Preview Pane an attack vector for this vulnerability?** No, the Preview Pane is not an attack vector.

**According to the CVSS, User Interaction is Required. What interaction would the user have to do?** Exploitation of the vulnerability requires that a target be lured to and make use of a specially crafted functionality on a SharePoint page created by the attacker. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to use the intended functionality.

**Why is Attack Complexity marked as High for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to take additional actions prior to exploitation to prepare the target environment.
