Cross-user history manipulation via unchecked authorization

Published Sep 22, 2025 · Updated Sep 22, 2025

Improper access control in Red Hat Enterprise Linux 9 and 10 allows local users to read, delete, or inject other users' chat history. Methods in com.redhat.lightspeed.history process IPC history requests without verifying that the caller owns the targeted history. Any unprivileged local account can plant deceptive commands in another user's stored prompts for later execution.
