CVE-2026-34354
HighSummary
Akamai Guardicore Platform Agent 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, enabling log file manipulation by unprivileged users.
Risk Assessment
This vulnerability can lead to unauthorized access to root-owned files, posing a serious security threat to organizational systems. Additionally, the command injection vulnerability in the gimmelogs tool increases the risk of privilege escalation.
Recommendation
It is recommended to update Akamai Guardicore Platform Agent to version 7.3.2 or later and Akamai Zero Trust Client to version 6.1.6 or later. Access to the /tmp directory should also be restricted, and the use of the gimmelogs tool should be monitored.

Original NVD description (English source)
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.
