high Tenable Self-Hosted Container Security Plugin ID 443670

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In Eclipse Theia versions prior to 1.71.0, the AI chat agent processed workspace file and directory names
 as part of its prompt context without distinguishing them from system instructions. An attacker could
 craft a malicious repository with adversarial directory or file names that, when analyzed by the AI agent,
 would cause the agent to follow attacker-controlled instructions (indirect prompt injection). Combined
 with other AI chat features available in untrusted workspaces, this enabled attack chains leading to data
 exfiltration via Markdown image rendering or arbitrary command execution via task definitions.
 (CVE-2026-44688)

Solution

Update the @theia/ai-chat library and its related packages to version 1.71.0 or later.
