CVE-2026-111079 Red Hat CVE debrief

Who should care

Defenders responsible for Red Hat Enterprise Linux 9 and 10 deployments that use Goose with terminal integration enabled should assess exposure and prioritize remediation to prevent sensitive information disclosure.

Why it matters

The flaw in Goose's terminal integration feature can lead to sensitive information disclosure, exposing confidential credentials to external service providers and logs. Defenders responsible for Red Hat Enterprise Linux 9 and 10 deployments that use Goose with terminal integration enabled should assess exposure and prioritize remediation.

• Potential exposure of confidential credentials to external service providers and logs.
• Possible unauthorized access to sensitive information.
• Required verification of Goose terminal integration feature usage and configuration.
• Necessity to sanitize shell command history and environment variables before sending to LLM provider endpoints.

Technical summary

The Goose application has a flaw in its terminal integration feature. When enabled, it captures shell command history and sends it verbatim without sanitization to configured Large Language Model (LLM) provider endpoints during queries. This can lead to sensitive information disclosure if users enter sensitive data like API tokens, passwords, or environment variables in the terminal. The flaw affects Red Hat Enterprise Linux 9 and 10 deployments that use Goose with terminal integration enabled, and defenders should prioritize verifying and remediating this vulnerability to prevent exposure of confidential credentials to external service providers and logs.

Defensive priority

Defenders should prioritize verifying and remediating this vulnerability in Red Hat Enterprise Linux 9 and 10 deployments that use Goose with terminal integration enabled.

Recommended defensive actions

• Verify Goose terminal integration feature usage in Red Hat Enterprise Linux 9 and 10 deployments.
• Sanitize shell command history and environment variables before sending to LLM provider endpoints.
• Restrict access to LLM provider endpoints to prevent unauthorized exposure.
• Monitor logs for potential sensitive information disclosure.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
