Channel Manager worker daemon — runs on remote machines to execute video pipeline jobs
AI Security Review
scanned 8d ago · by lpm-firewall-aiThis is a conditional command injection risk in the Windows agent lookup path, so the package warrants a warning. The source does not establish an unconsented attack chain that supports blocking publication.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Starting the Windows daemon with a crafted --nst-user value or a saved value that is used during agent lookup.
Impact
A crafted value may execute additional commands with the worker's account privileges; the inspected source does not establish a remote attacker-controlled input path.
Mechanism
The user name is inserted into a tasklist command string and passed to execSync.
AI rationale
This is a conditional command injection risk in the Windows agent lookup path, so the package warrants a warning. The source does not establish an unconsented attack chain that supports blocking publication.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The worker accepts the Nstbrowser user name from a command-line option or saved configuration.
- On startup, the daemon uses that configured name to resolve the matching local Nstbrowser agent.
- On Windows, the name is interpolated into a tasklist command that is executed through execSync without escaping.
- The lookup is limited to Windows, where a crafted name could cause shell command execution under the worker account.
