CVE-2026-46388 osquery CVE debrief

Who should care

Users of osquery versions prior to 5.23.1 should update to the latest version to prevent potential arbitrary file reads. This issue may impact operators responsible for maintaining osquery deployments, as well as security teams and vulnerability management teams that need to assess and mitigate this vulnerability.

Technical summary

An unprivileged attacker can read the contents of an osquery file carve until the carve completes and the temporary files are deleted. This is due to in-progress carve directories not being created with private permissions. If the carve targets a directory controlled by the attacker, arbitrary file reads are possible, potentially exposing sensitive local files. The issue impacts osquery deployments, particularly those with unprivileged access, and requires updating to version 5.23.1 or later to mitigate the vulnerability.

Defensive priority

Medium priority due to the potential for arbitrary file reads and the importance of maintaining the security and integrity of osquery deployments.

Recommended defensive actions

• Update osquery to version 5.23.1 or later
• Review and monitor osquery file carve operations
• Implement compensating controls to restrict access to sensitive files
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
