CVE-2018-1000176GHSA-gwxm-wqpq-w539
What to do
Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.jenkins-ci.plugins:email-ext 2.62), 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.
An exposure of sensitive information vulnerability exists in Jenkins Email Extension Plugin 2.61 and older in src/main/resources/hudson/plugins/emailext/ExtendedEmailPublisher/global.groovy and ExtendedEmailPublisherDescriptor.java that allows attackers with control of a Jenkins administrator's web browser (e.g. malicious extension) to retrieve the configured SMTP password.

# Patch Next advisory brief: CVE-2018-1000176 Advisory: Jenkins Email Extension Plugin showed plain text SMTP password in configuration form field IDs: CVE-2018-1000176, GHSA-gwxm-wqpq-w539 Record: https://patchnext.com/advisories/cve-2018-1000176 (revision 1, source checked 26 Oct 2026, 16:25 UTC) Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected. Severity: Medium (CVSS 6.5) 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:email-ext 2.62. A vendor fix does not mean a deployment is fixed. ## Affected components - Maven org.jenkins-ci.plugins:email-ext: affected <= 2.61; fixed in 2.62 ## Suggested inspection (read-only) - Maven org.jenkins-ci.plugins:email-ext: 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:email-ext. - 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-gwxm-wqpq-w539 (GitHub-reviewed advisory GHSA-gwxm-wqpq-w539 lists affected ranges: Maven org.jenkins-ci.plugins:email-ext >=0 <=2.61) Commands are suggestions: review each one before running it.
