Name of the Vulnerable Software and Affected Versions Eclipse Theia versions prior to 1.71.0
Description The AI chat agent processes workspace file and directory names as part of its prompt context without distinguishing them from system instructions. This allows for indirect prompt injection, where an attacker crafts a malicious repository with adversarial names that force the AI agent to follow attacker-controlled instructions. When used in untrusted workspaces, this can lead to attack chains resulting in arbitrary command execution via task definitions or data exfiltration through Markdown image rendering.
Recommendations Update to version 1.71.0 or later.
