建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
MISP 的事件删除逻辑中存在数据完整性缺陷。当用户删除某个事件时，部分关联记录未被从数据库中移除，从而形成孤立条目。受影响的记录类型包括：事件报告标签、事件图谱条目、提案（阴影属性）关联、模糊 ssdeep 关联块以及附件扫描结果。 这些孤立记录可能包含敏感的威胁情报数据，例如关联映射、扫描结果和报告元数据，本应随父事件一并删除。此类记录在预期删除生命周期之外持续存在，可能导致数据被意外保留，并可能通过其他应用程序查询或管理接口被访问，从而引发信息泄露风险。 前置条件： 拥有足够权限删除 MISP 中事件的已认证

Vulnerability Title
MISP Incomplete Event Deletion Leaves Orphaned Sensitive Records
来源: CVE Program / CVE List V5
Vulnerability Description
MISP contains a data integrity flaw in its event deletion logic. When a user deletes an event, several associated records are not removed from the database, leaving them as orphaned entries. The affected record types include event report tags, event graph entries, proposal (shadow attribute) correlations, fuzzy ssdeep correlation chunks, and attachment scan results.
These orphaned records may contain sensitive threat intelligence data such as correlation mappings, scan results, and report metadata that should have been removed along with the parent event. Their persistence beyond the intended deletion lifecycle creates a risk of unintended data retention and potential information exposure if the records are reachable through other application queries or administrative interfaces.
Preconditions:
- An authenticated user with sufficient privileges to delete events in MISP.
- The event must have associated reports, graphs, correlations, ssdeep chunks, or attachment scan results.
Impact:
- Residual sensitive data persists in the database after the parent event is deleted.
- Accumulation of orphaned records over time may contribute to storage bloat.
- Orphaned records may be inadvertently exposed through other data-access paths that do not validate the existence of the parent event.
Affected versions: <2.5.48
