Security readout for executives and security teams
Plain-English summary
CVE-2026-0924 is a high-severity local privilege escalation issue in Dr.Buho BuhoCleaner 1.15.2. A local unprivileged macOS user may be able to abuse an insecure XPC service and a PID reuse race condition to gain root privileges.
Executive priority
Prioritize remediation on Macs with multiple local users, developer workstations, privileged operator devices, or systems where compromise of a standard account could lead to broader environment access. Treat as important endpoint hardening rather than internet-edge emergency response unless local compromise is already suspected.
Technical view
The issue is described as an insecure XPC service in BuhoCleaner 1.15.2 that allows local privilege escalation to root through insecure functions. The assigned weakness is CWE-367, indicating a time-of-check/time-of-use race condition. CVSS v4.0 is 7.3 High with local attack vector, low attack complexity, low privileges required, no user interaction, and high confidentiality, integrity, and availability impact to the vulnerable system.
Likely exposure
Exposure is limited to systems with BuhoCleaner 1.15.2 installed, primarily macOS endpoints where local users or local code execution are possible. The CVSS vector is local, so this is not indicated as a network-remote vulnerability from the provided sources.
Exploitation context
The source bundle does not report known active exploitation, and KEV is false. Exploitation should be treated as local post-access privilege escalation: an attacker already needs a low-privileged local foothold or account on a host running the affected version.
Researcher notes
The provided bundle identifies only BuhoCleaner 1.15.2 as affected and states default status is unaffected for other versions. Patch evidence is limited to a vendor download URL tagged as patch; no fixed version is provided in the bundle, so remediation should be tied to vendor-confirmed guidance rather than an assumed version. External web search was not used because the user required use of only the supplied CVE source bundle.
Mitigation direction
- Inventory endpoints for Dr.Buho BuhoCleaner version 1.15.2 and prioritize shared, developer, admin-adjacent, or high-value Macs.
- Remove or disable BuhoCleaner 1.15.2 where it is not operationally required.
- Check Dr.Buho vendor guidance and the official download page for a fixed or newer build before upgrading; the bundle includes a patch-tagged download reference but does not specify a fixed version number.
- Restrict local interactive access to affected hosts and review whether untrusted users can run software on them.
- Monitor affected systems for unexpected privileged helper or XPC-service activity until remediation is confirmed.
Validation and detection
- Confirm whether BuhoCleaner 1.15.2 is installed on managed endpoints.
- Confirm the installed version after any vendor update and retain evidence of the vendor-stated fixed version or remediation guidance.
- Verify the vulnerable version is removed, upgraded, or otherwise not available to local unprivileged users.
- Validate that normal BuhoCleaner functionality still works after remediation without granting unintended privileged operations to standard users.
- Track the CVE record and vendor advisory for any later clarification on fixed versions or exploitation status.
