Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Jenkins S3 Explorer Plugin versions 1.0.8 and earlier does not mask the AWS_SECRET_ACCESS_KEY form field in its configuration UI, allowing the sensitive AWS secret key to be displayed in plaintext to users viewing the configuration page.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify S3 Explorer Plugin is installedNavigate to Jenkins > Manage Jenkins > Manage Plugins > Installed tab, or use the Jenkins CLI: java -jar jenkins-cli.jar list-plugins 2>/dev/null | grep -i 's3.*explorer'Affected if The plugin appears in the list of installed plugins
-
Confirm plugin version is vulnerableIn Manage Plugins > Installed, check the version column for S3 Explorer Plugin, or check the plugin's pom.xml or manifest if extracted from the .hpi fileAffected if Version is 1.0.8 or earlier (any version up to and including 1.0.8)
-
Check if S3 Explorer is configuredNavigate to Jenkins > Manage Jenkins > Configure System and look for the S3 Explorer section, or go to the plugin's dedicated configuration page if one existsAffected if The plugin has an AWS_SECRET_ACCESS_KEY field populated in the configuration
-
Inspect if secret key is plaintextIn the S3 Explorer configuration page, view the AWS_SECRET_ACCESS_KEY field - if it shows readable text characters instead of masked dots or asterisks, the vulnerability is presentAffected if The AWS secret key field displays as plaintext (not masked with dots, asterisks, or password-type input)
If the S3 Explorer Plugin version is 1.0.8 or earlier and has a configured AWS_SECRET_ACCESS_KEY that displays in plaintext, the environment is affected by this CVE.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to a patched version of the S3 Explorer Plugin that masks the AWS_SECRET_ACCESS_KEY field. If no patch is available, restrict access to the plugin configuration page to trusted administrators only.
