CVE-2020-2140
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 Audit Trail Plugin 3.2 and earlier does not escape the error message for the URL Patterns field form validation, resulting in a reflected cross-site scripting vulnerability.
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 Audit Trail Plugin versions 3.2 and earlier does not escape output in error messages displayed during form validation for the URL Patterns field, resulting in a reflected cross-site scripting (XSS) vulnerability. An attacker can inject malicious JavaScript into the URL Patterns field that executes when form validation fails and displays the unescaped error message to the victim.

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.
-
