CVE-2025-53667
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedJenkins Dead Man's Snitch Plugin 0.1 does not mask Dead Man's Snitch tokens displayed on the job configuration form, increasing the potential for attackers to observe and capture them.
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 Dead Man's Snitch Plugin version 0.1 displays Dead Man's Snitch API tokens in plain text on the job configuration form instead of masking them as sensitive credentials. Attackers with access to view or configure jobs can observe and capture these tokens, potentially gaining unauthorized access to the monitoring service.

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 Dead Man's Snitch plugin is installedIn Jenkins, go to Manage Jenkins > Manage Plugins > Installed and search for 'Dead Man\'s Snitch' or check the plugin directory for the hpi fileAffected if The plugin is listed as version 0.1
-
Confirm plugin version is 0.1In the installed plugins list, verify the exact version number shown for the Dead Man's Snitch pluginAffected if Version column shows exactly 0.1
-
Identify jobs using Dead Man's SnitchSearch job configurations or examine config.xml files for '<deadMansSnitch>' or related configuration blocks that reference the pluginAffected if One or more jobs have Dead Man's Snitch configuration enabled with an API token field
-
Check if tokens are maskedOpen a configured job's configuration page and locate the Dead Man's Snitch API token field - observe whether the input appears as masked (dots/asterisks) or plain textAffected if The API token field displays characters in plain text rather than masked input

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 dataApply the latest plugin update when available that masks tokens as sensitive fields, or restrict job configuration access to trusted users only until a patch is released.
