Name of the Vulnerable Software and Affected Versions
MISP (affected versions not specified)
Description
An improper authorization check in the attribute creation endpoint allows an authenticated user with permissions to add attributes to submit a
sharing group id without triggering the required authorization check, provided the attribute distribution value is not set to 4 (sharing group). This access-control bypass enables users to associate attributes with sharing groups they are not authorized to use, potentially compromising the integrity of sharing metadata and exposing restricted sharing group relationships.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
