Description
Description
Affected versions of MISP’s interactive CLI shell implement access control independently from the normal web application, causing several authorization inconsistencies.
The patch shows that CLI access could differ from the web application in multiple security-sensitive areas:
- feed listings did not enforce the same lookup_visible restrictions for non-host-organisation users;
- feed detail access did not enforce the same host-organisation/site-admin authorization as FeedsController::view();
- Feed.headers, which can contain HTTP authorization credentials, could be exposed instead of being hidden or masked;
- server synchronization authkey values were not explicitly hidden from CLI detail output;
- sharing-group detail access did not consistently use SharingGroup::checkIfAuthorised();
- the use command could establish context for a record without first proving that the user was authorized to view that record
The commit additionally hardens pagination and terminal rendering, including neutralization of terminal control sequences found in database-backed values. Those are important hardening changes, but the main vulnerability is the CLI authorization/data-disclosure mismatch.

CWE
KEV
| CWE ID | Description |
|---|---|
| CWE-522 | The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval. |
| CWE-862 | The product does not perform an authorization check when an actor attempts to access a resource or perform an action. |
| CWE-150 | The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as escape, meta, or control character sequences when they are sent to a downstream component. |
| CWE-200 | The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. |
