Priority Score
Attack Technique
Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
