CVE-2026-34354

The record

Akamai Guardicore Platform Agent (GPA) and Zero Trust Client on Linux and macOS allow TOCTOU-based local privilege escalation. The GPA service creates an IPC socket in the world-writable /tmp directory. It accepts unauthenticated IPC control messages. This enables a TOCTOU vulnerability in the HandleSaveLogs() function of the GPA service, by creating a log file and manipulating it into a symlink that points to the targeted path; this can allow an unprivileged local user to make arbitrary root-owned files world-writable. In addition, a diagnostic collection tool (gimmelogs) running with root privileges was vulnerable to command injection from the dbstore, offering a second privilege escalation vector. (On Windows, gimmelogs does not have command injection but does allow writing a ZIP archive to an unintended location.) This affects Akamai Guardicore Platform Agent 7.0 through 7.3.1 and Akamai Zero Trust Client 6.0 through 6.1.5.
