- Attack vector (AV:L)
- They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
- Attack complexity (AC:H)
- Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
- Privileges required (PR:N)
- No account or special rights needed—anonymous or random user is enough.
- User interaction (UI:R)
- A real person has to do something—click, install, enable—otherwise it doesn’t land.
- Scope (S:U)
- Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
- Confidentiality (C:H)
- Serious risk that confidential data gets exposed in a big way.
- Integrity (I:H)
- They could widely tamper with or forge data—trust in the data is badly hurt.
- Availability (A:H)
- Could take the service down hard or make it unusable for people who depend on it.
