CVE-2026-82518: Akamai CLI file overwrite in cli.json (high)

Summary

Akamai CLI before 2.0.6 contains a path traversal vulnerability that allows malicious packages to write files outside the install directory via unvalidated commands[].name values in cli.json. Attackers who convince victims to install or update a package can use '..' segments to overwrite executables on the user's PATH, persisting after uninstall.

What to do

Check whether your setup matches what the bug needs.
Akamai CLI version before 2.0.6 Victim must install or update a malicious package
Upgrade to a fixed version: 2.0.6.

Check your systems with an agent

Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.

Check whether my systems are affected by CVE-2026-82518 (Akamai CLI before 2.0.6 Path Traversal via cli.json Command Names), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

CISA KEV: CVE-2026-82518 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-82518 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:
- https://github.com/akamai/cli/pull/227
- https://github.com/akamai/cli/commit/03cf2e4d7db3680ee8230aa399697d74b0ec5244

Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

Questions about CVE-2026-82518

Is CVE-2026-82518 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data

What does this mean?

A path traversal flaw in how Akamai CLI handles command names from cli.json lets malicious packages write files outside the install directory. This can include overwriting executables on the user's PATH, and the changes persist after uninstall.Source: vulncheck.com

Which versions are affected by CVE-2026-82518?

Akamai CLI: before 2.0.6.Source: cve.now feed data

Am I affected, and how do I check?

Akamai CLI versions before 2.0.6 are affected. The issue requires installing or updating a malicious package, and the installed Akamai CLI version is the thing to check against 2.0.6.Source: vulncheck.com

How do I fix CVE-2026-82518?

Upgrade Akamai CLI to version 2.0.6 or later, which contains the fix.Source: vulncheck.com
