CVE-2026-88391
validatedZero produced an exploit or a check.GHSA-8hhc-85h8-34q6 ↗EUVD-2026-92443 ↗
description
dromara Northstar versions through 9.1.1 expose the embedded H2 console without authentication. An attacker who can reach that endpoint over the network can access the database using default credentials and execute commands on the host.
mitigation
Disable the H2 console in deployed Northstar instances and block network access to its console endpoint. Restrict the service to trusted networks until an upstream fixed release is available.
outcome
Check only, differential: the check fires on the vulnerable build and is silent on the patched one.
source signals
Public signals that triggered or updated the pipeline. These are inputs for the deltas above.
