launch-editor: NTLMv2 hash disclosure via UNC path handling on Windows
GitHub lists this reviewed advisory for launch-editor, vite, vite, vite, vite-plus. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.
launch-editor
source listed<= 2.14.0
### Summary The `launch-editor` NPM package accesses arbitrary paths including Windows UNC paths. When a UNC path is opened, Windows automatically attempts NTLM authentication to the remote host, causing the user’s NTLMv2 password hash to be leaked to an attacker-controlled SMB server. This can result in credential compromise through offline hash cracking. ### Impact If the following conditions are met, an attacker can get the NTLMv2 password hash on the computer that is using the `launch-editor`: - using Windows - NTLM is not disabled (it is recommended to disable, while it's still enabled by default) - the user accesses the attackers website that sends request to a middleware using `launch-editor` - the server that has the middleware using `launch-editor` is running - the attacker knows the URL for that server and the middleware This would be a problem if the user password is too simple that it can be identified through offline hash cracking, potentially leading to further compromise of developer accounts or internal systems. ### Details `launch-editor`

03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
