Description

Build readers can access another repository's environment properties. A caller with read access to an ordinary repository can select a readable repository parameter while retrieving environment properties for a protected build, exposing build environment secrets (confidentiality impact; no integrity or availability impact demonstrated).

In plain language

AI Act now

In JFrog Artifactory, a person who can read an ordinary repository may be able to view secret “build environment” settings from another (protected) build—so if you run Artifactory, you should act fast and upgrade.

Executive summary

CVE-2026-66018 is a JFrog Artifactory information exposure weakness (CWE-200) where users with read permissions to one repository can retrieve environment properties for a protected build in another repository, exposing build environment secrets; exploitation has been reported in the real world.

What to do now

  1. Check your JFrog Artifactory version number (from the application’s “About” page or server logs/config).
  2. If your Artifactory version is older than the fix, upgrade to one of the fixed releases: 7.146.34 or 7.161.15.
  3. Review who has “read” access to repositories: reduce read permissions so fewer users/services can access repositories they shouldn’t.
  4. If you use build environment properties for tokens, passwords, or API keys, rotate those secrets after upgrading (start with any secrets used by builds you consider high value).
Usually a quick update
