CVE-2026-105628— Plane: OAuth Avatar Redirect SSRF Leads to Internal Data Exfiltration via Static Asset Endpoint

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 是一款开源的项目管理工具。在 1.4.0 版本之前，Plane 的 OAuth 头像同步流程通过服务器端 HTTP 请求从提供商用户数据中获取 ，未对内部 IP 地址进行验证，并且默认遵循重定向。攻击者可以提供重定向到仅限内部访问的资源（如元数据端点）的头像 URL，Plane 会将获取到的响应内容作为用户头像文件上传。该资源随后通过 路径暴露，从而导致可被利用来窃取内部获取的内容。此问题已在 1.4.0 版本中修复。

Vulnerability Title
Plane: OAuth Avatar Redirect SSRF Leads to Internal Data Exfiltration via Static Asset Endpoint
Source: CVE Program / CVE List V5
Vulnerability Description
Plane is an open-source project management tool. Prior to 1.4.0, Plane's OAuth avatar synchronization flow fetches avatar_url from provider user data through a server-side HTTP request without internal IP validation and follows redirects by default. An attacker can provide an avatar URL that redirects to an internal-only resource, such as a metadata endpoint, and Plane uploads the fetched response as a user avatar file. The object is then exposed through /api/assets/v2/static/{asset_id}/, allowing exfiltration of internally fetched content. This issue is fixed in 1.4.0.
