FAQ
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 in order for an unauthenticated attacker to 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.
