CVE-2026-95674— MISP EventsController queryEnrichment allows querying unavailable or legacy modules without validation

Quick assessment

Affected
MISP MISP
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 MISP 系统中， 文件中的 方法接收一个模块名称参数，并遍历已启用的模块列表以查找匹配项。如果指定的模块未出现在已启用模块列表中，代码会静默地使用默认参数继续处理（格式设置为“simplified”，且不应用任何模块特定的配置），而不是拒绝该请求。这允许经过身份验证的用户通过一个未在实例上明确启用或可用的模块触发数据丰富或分析处理，从而绕过了预期的模块可用性控制机制。由于缺乏充分的验证，非启用集中的模块名称未被拒绝，可能导致管理员未授权使用的功能或数据处理路径被暴露。

Vulnerability Title
MISP EventsController queryEnrichment allows querying unavailable or legacy modules without validation
Source: CVE Program / CVE List V5
Vulnerability Description
In MISP, the queryEnrichment method in EventsController.php accepted a module name parameter and iterated over the list of enabled modules to find a match. If the specified module was not present in the enabled modules list, the code silently continued processing using default parameters (format set to 'simplified' and no module-specific configuration applied) rather than rejecting the request. This allowed an authenticated user to trigger enrichment or analysis processing through a module that was not explicitly enabled or available on the instance, bypassing the intended module availability controls. The lack of validation meant that module names outside the enabled set were not rejected, potentially exposing functionality or data processing paths that the administrator had not authorized for use.
