☕org.jenkins-ci.plugins:requests

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 requests-plugin Plugin 2.2.6 and earlier does not perform a permission check in an HTTP endpoint.

This allows attackers with Overall/Read permission to view the list of pending requests.

Jenkins requests-plugin Plugin 2.2.7 requires Overall/Administer permission to view the list of pending requests.

The previous sentence originally stated that Overall/Read permission was newly required. This statement was incorrect and has been fixed on 2021-07-05.

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:requests, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.plugins:requests to 2.2.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2021-21674 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.
