MISP 的组织模型中的 方法存在授权缺陷。当 参数设置为 时，该方法会在未验证调用用户是否拥有足够权限的情况下，无条件覆盖组织元数据字段。具有共享组（SG）编辑者角色的用户可触发此代码路径，从而能够修改本应仅限站点管理员或拥有同步权限的用户才能更改的组织元数据。 根据提交信息，此漏洞可能导致基于蓝图（blueprint）的共享组被恶意操控。这意味着，拥有 SG 编辑者访问权限的攻击者可以以影响共享组和蓝图在整个 MISP 实例中行为的方式，篡改组织属性。 该漏洞要求攻击者必须是已认证用户，且至少具备 SG 编辑者

Vulnerability Title
MISP: Insufficient Authorization Allows Sharing Group Editors to Overwrite Organization Metadata
Source: CVE Program / CVE List V5
Vulnerability Description
MISP contains an authorization flaw in the Organisation model's captureOrg method. When the $force parameter is set to true, the method unconditionally overwrites organization metadata fields without verifying that the invoking user holds sufficient privileges. A user with a sharing group (SG) editor role can trigger this code path, allowing them to modify organization metadata that should be restricted to site administrators or users with sync permissions. According to the commit message, this could lead to blueprint-based sharing group manipulation, meaning an attacker with SG editor access could alter organizational attributes in ways that influence how sharing groups and blueprints behave across the MISP instance.  The vulnerability requires an authenticated user with at least SG editor privileges and network access to the MISP web interface. The impact is primarily on the integrity of organization records and, potentially, on the integrity of sharing group configurations derived from those records.
