Cross-Site Request Forgery in Jenkins Credentials Plugin

CVE-2021-21648GHSA-gchq-9r68-6jwv

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.jenkins-ci.plugins:credentials 2.3.19, 2.3.15.1, 2.3.14.1, 2.3.13.1, 2.3.7.1, 2.3.0.1), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Jenkins Credentials Plugin prior to 2.3.19, 2.3.15.1, 2.3.14.1, 2.3.13.1, 2.3.7.1, and 2.3.0.1 does not escape user-controlled information on a view it provides, resulting in a reflected cross-site scripting (XSS) vulnerability. Jenkins Credentials Plugin 2.3.19, 2.3.15.1, 2.3.14.1, 2.3.13.1, 2.3.7.1, and 2.3.0.1 restricts the user-controlled information it provides to a safe subset.

# Patch Next advisory brief: CVE-2021-21648

Advisory: Cross-Site Request Forgery in Jenkins Credentials Plugin
IDs: CVE-2021-21648, GHSA-gchq-9r68-6jwv
Record: https://patchnext.com/advisories/cve-2021-21648 (revision 1, source checked 26 Oct 2026, 16:24 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.jenkins-ci.plugins:credentials 2.3.19, 2.3.15.1, 2.3.14.1, 2.3.13.1, 2.3.7.1, 2.3.0.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.jenkins-ci.plugins:credentials: affected >= 2.3.16, < 2.3.19; >= 2.3.15, <= 2.3.15; >= 2.3.14, <= 2.3.14; >= 2.3.8, < 2.3.13.1; >= 2.3.1, < 2.3.7.1; < 2.3.0.1; fixed in 2.3.19, 2.3.7.1, 2.3.15.1, 2.3.14.1, 2.3.13.1, 2.3.0.1

## Suggested inspection (read-only)
- Maven org.jenkins-ci.plugins:credentials: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.jenkins-ci.plugins:credentials.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
