Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Apache Syncope 中存在授权不当漏洞。 委托管理的安全检查基于 Realm 层级结构，并通过前缀匹配来强制执行。由于实现存在缺陷，两个名称以相同字符串开头的同级 Realm 无法被正确区分，从而导致授权判断出现错误。 此问题影响 Apache Syncope 的以下版本：3.0.0-M0 至 3.0.16，4.0.0-M0 至 4.0.7，以及 4.1.0-M0 至 4.1.2。 建议用户升级至 4.0.8 或 4.1.3 版本，该版本已修复此问题。
