Description
Attackers can create/override arbitrary files with uncontrolled data.
For a PoC, spin up an instance of soft-serve as explained in the README, and execute the following command:
ssh -p23231 localhost repo commit icecream -- --output=/tmp/pwned
It should have created a file in /tmp/pwned.

Click to expand
- Attack vector (AV:N)
- Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
- Attack complexity (AC:L)
- Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
- Privileges required (PR:L)
- A normal user session is enough; they don’t have to be admin.
- User interaction (UI:N)
- Nobody has to click “OK” or open a trap file; it can work without a victim helping.
- Scope (S:C)
- Breaking this can reach past the original component and bite other resources—bigger blast radius.
- Confidentiality (C:N)
- Doesn’t really leak secrets in a meaningful way.
- Integrity (I:H)
- They could widely tamper with or forge data—trust in the data is badly hurt.
- Availability (A:N)
- Service keeps running; no real outage angle.
