CVE-2026-0598
Description
A security flaw was identified in the Ansible Lightspeed API conversation endpoints that handle AI chat interactions. The APIs do not properly verify whether a conversation identifier belongs to the authenticated user making the request. As a result, an attacker with valid credentials could access or influence conversations owned by other users. This exposes sensitive conversation data and allows unauthorized manipulation of AI-generated outputs.
Statement
This vulnerability is rated Moderate for Red Hat. The flaw in Ansible Lightspeed API conversation endpoints allows an authenticated attacker to access or influence other users' AI chat sessions due to improper ownership validation of conversation identifiers. This can lead to unauthorized information disclosure and manipulation of AI-generated outputs.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
