📋 Description

According to the CVSS metric, the attack vector is network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution? This attack requires an authenticated client to click a link so that an unauthenticated attacker can initiate remote code execution.

How could an attacker exploit the vulnerability? An attacker could exploit the vulnerability by controlling subsequent memory allocation after a double free error occurs. This could potentially allow the attacker to execute arbitrary code, leading to remote code execution.
