FAQ: 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. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.
FAQ: According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?
An attacker must send the user a malicious file and convince them to open it.

CVE-2023-32029 [HIGH] Two remote code execution vulnerabilities disclosed in Microsoft Excel
Cisco Talos recently discovered two vulnerabilities in the Microsoft Excel spreadsheet management software that could allow a malicious actor to execute arbitrary code on the targeted machine.
Microsoft disclosed these issues and patched them as part of June’s monthly security release for the company.
One of the vulnerabilities, TALOS-2023-1730 (CVE-2023-32029), exists in the FreePhisxdb function of Excel. An attacker could exploit this vulnerability by tricking the targeted user into opening a specially crafted file. Then, they can manipulate the heap to gain the ability to execute arbitrary code.
TALOS-2023-1734 (CVE-2023-33133) works similarly, but in this case, causes an out-of-bounds read that turns into an out-of-bounds write, which in turn, could lead to memory corruption and, fi
