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

Health Advisor by CloudBees Plugin 3.0 and earlier does not perform permission checks in methods performing form validation. This allows users with Overall/Read access to send an email with fixed content to an attacker-specified recipient.

Additionally, these form validation methods do not require POST requests, resulting in a CSRF vulnerability.

Health Advisor by CloudBees Plugin 3.0.1 requires POST requests and Overall/Administer permission for the affected form validation methods.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update org.jenkins-ci.plugins:cloudbees-jenkins-advisor to 3.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2020-2093 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
