CVE-2026-105629— Plane: Cross-Tenant Destructive IDOR: Estimate Point Deletion via Unscoped Primary Key Lookup

Quick assessment

Affected
makeplane plane
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.

Plane 是一款开源项目管理工具。在 1.4.0 版本之前， 接口通过简单的 primary key（主键）查询来定位估算点（estimate point），未进行工作区（workspace）、项目（project）或估算作用域（estimate scoping）的权限校验。攻击者可以通过向其所在的工作区下的 URL 中传入目标估算点的 UUID，永久删除属于其他工作区的估算点。该问题构成了一种破坏性的跨租户越权访问漏洞（IDOR）。此漏洞已在 1.4.0 版本中修复。

Vulnerability Title
Plane: Cross-Tenant Destructive IDOR: Estimate Point Deletion via Unscoped Primary Key Lookup
Source: CVE Program / CVE List V5
Vulnerability Description
Plane is an open-source project management tool. Prior to 1.4.0, BulkEstimatePointEndpoint.destroy resolves an estimate point through a bare primary-key lookup without workspace, project, or estimate scoping. An administrator or member of one workspace can permanently delete an estimate point belonging to another workspace by supplying the target UUID in a URL under the attacker's own workspace. This creates a destructive cross-tenant IDOR. This issue is fixed in 1.4.0.
