CVE-2026-25807 | Unauthenticated Remote Code Execution via P2P Sharing in ZAI-Shell

Exp

ZAI Shell is an autonomous SysOps agent designed to navigate, repair, and secure complex environments. Prior to 9.0.3, the P2P terminal sharing feature (share start) opens a TCP socket on port 5757 without any authentication mechanism. Any remote attacker can connect to this port using a simple socket script. An attacker who connects to a ZAI-Shell P2P session running in --no-ai mode can send arbitrary system commands. If the host user approves the command without reviewing its contents, the command executes directly with the user's privileges, bypassing all Sentinel safety checks. This vulnerability is fixed in 9.0.3.

Base score Version Severity Vector Exploitability Impact Score source
8.8 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H 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: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.
