CVE-2019-8157
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 · uneditedA stored cross-site scripting (XSS) vulnerability exists in Magento 2.2 prior to 2.2.10, Magento 2.3 prior to 2.3.3 or 2.3.2-p1. An authenticated user can manipulate downloadable link and cause an invocation of error handling that acceses user input without sanitization.
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 · moderate confidenceA stored cross-site scripting (XSS) vulnerability in Magento 2 allows authenticated users to inject malicious JavaScript through manipulable downloadable link fields. When error handling processes user input without proper sanitization, the payload gets stored and executes when other users view the affected content.

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.
-
Identify Magento versionRun command: php bin/magento --version or check composer.json for 'version' fieldAffected if Installed version is >= 2.2.0 and < 2.2.10, OR >= 2.3.0 and < 2.3.3 (including 2.3.2)
