CVE-2026-61474
MediumCVSS 5.3Summary
An improper authorization check in MISP's attribute creation endpoint allowed an authenticated user with permission to add attributes to submit a sharing_group_id without triggering the corresponding sharing group authorization check, as long as the attribute distribution value was not explicitly set to 4 — 'sharing group'.
Risk Assessment
The risk is an access-control bypass that could lead to unauthorized association of attributes with sharing groups, compromising the integrity of sharing metadata and potentially exposing or misusing restricted sharing group relationships.
Recommendation
Apply the available patch immediately, which changes the authorization logic to perform the sharing group permission check whenever a non-empty sharing_group_id is provided, regardless of the selected distribution value.
Other vulnerabilities in MISP
See all- CVE-2017-14337High

Original NVD description (English source)
An improper authorization check in MISP’s attribute creation endpoint allowed an authenticated user with permission to add attributes to submit a sharing_group_id without triggering the corresponding sharing group authorization check, as long as the attribute distribution value was not explicitly set to 4 — “sharing group”. As a result, a user could reference or associate an attribute with a sharing group they were not authorized to use. This could lead to an access-control bypass affecting the integrity of attribute sharing metadata and potentially expose or misuse restricted sharing group relationships. The patch changes the authorization logic so that the sharing group permission check is performed whenever a non-empty sharing_group_id is provided, regardless of the selected distribution value.
