Detailsinfo

A vulnerability classified as critical was found in Intego Log Reporter up to 10.9.x on macOS. This vulnerability affects an unknown code block of the file /tmp. The manipulation with an unknown input leads to a toctou vulnerability. The CWE definition for the vulnerability is CWE-367. The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Intego Log Reporter, a macOS diagnostic utility bundled with Intego security products that collects system and application logs for support analysis, contains a local privilege escalation vulnerability. A root-executed diagnostic script creates and writes files in /tmp without enforcing secure directory handling, introducing a time-of-check to time-of-use (TOCTOU) race condition. A local unprivileged user can exploit a symlink-based race condition to cause arbitrary file writes to privileged system locations, resulting in privilege escalation to root.

The weakness was released by Mathieu Farrell. The advisory is available at blog.quarkslab.com. This vulnerability was named CVE-2026-26224 since 02/11/2026. The exploitation appears to be easy. Local access is required to approach this attack. Technical details are known, but there is no available exploit.
