CVE-2025-5962: Rhel-lightspeed: improper access control in lightspeed history management allows local privilege manipulation
A flaw was found in the Lightspeed history service. Insufficient access controls allow a local, unprivileged user to access and manipulate the chat history of another user on the same system. By abusing inter-process communication calls to the history service, an attacker can view, delete, or inject arbitrary history entries, including misleading or malicious commands. This can be used to deceive another user into executing harmful actions, posing a risk of privilege misuse or unauthorized command execution through social engineering.
Security readout for executives and security teams
Plain-English summary
A local user on an affected RHEL system can interfere with another user's Lightspeed command-line assistant history. That history could be viewed, deleted, or altered to place misleading entries that encourage harmful actions.
Executive priority
Treat as high priority for shared Linux environments and administrative hosts. It is not described as remotely exploitable, but it can undermine trust in command history and support privilege misuse through deception.
Technical view
The flaw is improper access control in Lightspeed history management for command-line-assistant on RHEL 9 and 10. Unprivileged local users can abuse IPC access to the history service to read, delete, or inject another user's history entries.
Likely exposure
Exposure is limited to systems running affected Red Hat Enterprise Linux 9 or 10 command-line-assistant packages, especially shared servers, jump hosts, and administrator workstations where multiple local users use Lightspeed.
Exploitation context
The bundle reports local access and no KEV listing. It does not provide evidence of active exploitation. Impact depends on shared local access and whether tampered history can influence privileged users' actions.
Researcher notes
Sources identify CWE-284, CVSS 7.7, and affected package builds. The bundle does not include fixed package versions, proof-of-concept status, or confirmed exploitation, so remediation should track Red Hat advisories directly.
Mitigation direction
Inventory RHEL 9 and 10 hosts with command-line-assistant installed.
Check Red Hat RHSA-2025:16345 and RHSA-2025:16346 for approved updates.
Apply vendor guidance before relying on local compensating controls.
Limit unnecessary local shell access on shared administrative systems.
Warn privileged users not to trust command history entries blindly.
Validation and detection
Confirm installed command-line-assistant package versions on RHEL 9 and 10 systems.
Compare package status against Red Hat advisories for this CVE.
Review local account access on systems where Lightspeed is used.
Check whether affected systems are shared by privileged and unprivileged users.

Improper Access Control
Improper Access Control represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
