CVE-2026-90895

/// Technical 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.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;
