CVE-2026-44691

Quick assessment

Affected
Eclipse Foundation Eclipse Theia
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.

Eclipse theia是美国Eclipse基金会开源的一个可扩展的开发环境框架。 Eclipse theia 1.69.0之前版本存在软件供应链问题漏洞，该漏洞源于工作区文件中的自定义任务定义（如.theia/tasks.json、.vscode/tasks.json）可在无需工作区信任的情况下执行，可能导致攻击者利用恶意仓库克隆并打开后以用户权限执行任意命令。结合AI聊天功能及禁用了工具确认的工作区设置文件，可通过发送消息自动触发该漏洞。

Source: CVE Program / CVE List V5
Vulnerability Description
In Eclipse Theia versions prior to 1.69.0, custom task definitions in workspace files (e.g. .theia/tasks.json, .vscode/tasks.json) could be executed without requiring workspace trust. An attacker could craft a malicious repository that, when cloned and opened in Theia, leads to execution of arbitrary commands with the user's privileges. In combination with AI chat features and a workspace .theia/settings.json that disabled tool confirmation, this could be triggered automatically by sending a message in the AI chat.
