What is CVE-2026-44691?

CVE-2026-44691 is a high-severity security vulnerability in @theia/debug (npm), affecting versions < 1.69.0. It is fixed in 1.69.0.

Which packages are affected by CVE-2026-44691?

@theia/debug (npm) versions < 1.69.0; @theia/task (npm) versions < 1.69.0; @theia/workspace (npm) versions < 1.69.0.

Is there a fix for CVE-2026-44691?

Yes. CVE-2026-44691 is fixed in 1.69.0. Upgrade to this version or later.

Is CVE-2026-44691 exploitable, and should I be worried?

Whether CVE-2026-44691 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether CVE-2026-44691 is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

Summary

[Eclipse Theia] Arbitrary Command Execution via Untrusted Workspace Task Definitions

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.

Impact

Affected versions

@theia/debug (< 1.69.0) @theia/task (< 1.69.0) @theia/workspace (< 1.69.0)

Security releases

@theia/debug → 1.69.0 (npm) @theia/task → 1.69.0 (npm) @theia/workspace → 1.69.0 (npm)

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
