CVE-2026-44691 – Eclipse Theia Workspace Trust Bypass via Malicious Task Definitions

CVE ID :CVE-2026-44691

Published : June 18, 2026, 2:35 p.m. | 1 hour, 7 minutes ago

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.

Severity: 8.4 | HIGH
