CVE-2026-82518: Akamai CLI path traversal in package installation

CVE-2026-82518 · Severity: medium · CVSS 6.5 · Published 2026-11-10

Akamai CLI is a command-line management tool that installs packages containing command extensions. A path traversal vulnerability in how it processes package metadata allows attackers to place malicious executables outside the intended installation directory, potentially overwriting legitimate programs on the user's system. An attacker who tricks a user into installing a malicious package can persistently compromise the system with code that survives uninstallation.

Vendors: Akamai.

How to fix

  • Fixed in: 2.0.6

Technical details

The vulnerability exists in the package installation flow where the commands[].name value from cli.json is accepted without validating for path traversal sequences (../, absolute paths, or path separators). This name parameter is later used directly as a filesystem path component when writing installed command binaries, allowing an attacker to write files outside the package directory. The flaw occurs during Akamai CLI's own installation logic, before the user ever executes the installed command, driven purely by metadata in the package.
