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.

Omnispace Agora Project 版本 26.10.0 之前存在一个访问控制缺陷漏洞。该漏洞允许空间管理员在未经授权的情况下，将用户分配到其权限范围之外的空间中，原因是执行 spaceAffectList 分配时未验证调用方对目标空间的操作权限。攻击者可通过利用导入流程中 join INSERT 操作中缺失的 readRight() 检查，破坏租户隔离性，并篡改用户对非授权空间的分配关系。

Vulnerability Title
Omnispace Agora Project < 26.10.0 Broken Access Control via spaceAffectList
Source: CVE Program / CVE List V5
Vulnerability Description
Omnispace Agora Project before 26.10.0 contains a broken access control vulnerability that allows a space administrator to assign users into spaces outside their authority because the spaceAffectList affectation was performed without verifying the caller's rights to the target space. Attackers can exploit the missing readRight() check in the import flow's join INSERT to break tenant isolation and manipulate user-space assignments across unauthorized spaces.
