EPSS

• CVE-2023-37947: 0.56% estimated exploitation activity in the next 30 days; percentile 46.54 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Jenkins OpenShift Login Plugin 1.1.0.227.v27e08dfb1a20 and earlier improperly determines that a redirect URL after login is legitimately pointing to Jenkins. This allows attackers to perform phishing attacks by having users go to a Jenkins URL that will forward them to a different site after successful authentication. OpenShift Login Plugin 1.1.0.230.v5d7030bf5432 only redirects to relative (Jenkins) URLs.

# Patch Next advisory brief: CVE-2023-37947

Advisory: Jenkins OpenShift Login Plugin vulnerable to Open Redirect
IDs: CVE-2023-37947, GHSA-35gf-xjgf-96c5
Record: https://patchnext.com/advisories/cve-2023-37947 (revision 1, source checked 26 Oct 2026, 16:16 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.openshift.jenkins:openshift-login 1.1.0.230.v5d7030b. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.openshift.jenkins:openshift-login: affected < 1.1.0.230.v5d7030b; fixed in 1.1.0.230.v5d7030b

## Suggested inspection (read-only)
- Maven org.openshift.jenkins:openshift-login: 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.openshift.jenkins:openshift-login.
- 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.

## Sources
- Verified: https://github.com/advisories/GHSA-35gf-xjgf-96c5 (GitHub-reviewed advisory GHSA-35gf-xjgf-96c5 lists affected ranges: Maven org.openshift.jenkins:openshift-login >=0 <1.1.0.230.v5d7030b)
