## JFrog Artifactory Improper Limitation of a Pathname to a Restricted Directory Vulnerability
Severity: high, exploited in the wild. Patch status: patched.
Affected: JFrog Artifactory
Ids: CVE-2026-66384

JFrog Artifactory contains an improper limitation of a pathname to a restricted directory vulnerability. This can allow an authenticated user to write data outside the intended Docker cache path under specific remote-repository conditions. Added to CISA KEV on 2026-08-27 (federal deadline 2026-09-10).

## Steps
1. Check Dockerfiles, compose files and Kubernetes or Helm manifests for affected images and tags. Report the tag in use and the first fixed tag.
2. This touches infrastructure (ci). Look in terraform, ansible, cloud-init, Dockerfiles and docs for the product and version we run. If it isn't in the repo, say so and list what a human should check on the box.

## Report
A table: file, product or package, version in use, affected yes/no, exact fix. Then anything a human has to check outside the repo.
