Real-World Exposure

1 pkg affected
☕hudson.plugins:project-inheritance

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

Jenkins limits access to job configuration XML data (config.xml) to users with Job/ExtendedRead permission, typically implied by Job/Configure permission. Project Inheritance Plugin has several job inspection features, including the API URL /job/…​/getConfigAsXML for its Inheritance Project job type that does something similar.

Project Inheritance Plugin 21.04.03 and earlier does not check permissions for this new endpoint, granting access to job configuration XML data to every user with Job/Read permission.

Additionally, the encrypted values of secrets stored in the job configuration are not redacted, as they would be by the config.xml API for users without Job/Configure permission.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for hudson.plugins:project-inheritance, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of hudson.plugins:project-inheritance for CVE-2020-2197. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    Close the privilege gap rather than the entry point: audit which accounts, roles and service identities can reach the affected operation, drop the component to the least privilege it actually needs, and review file and directory permissions created by earlier installs — a default left in place is what makes this reachable.
