CVE-2019-7881
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 cross-site scripting mitigation bypass exists in Magento 2.1 prior to 2.1.18, Magento 2.2 prior to 2.2.9, Magento 2.3 prior to 2.3.2. This could be exploited by an authenticated user to escalate privileges (admin vs. admin XSS attack).
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 confidenceThis is a cross-site scripting (XSS) mitigation bypass in Magento 2 e-commerce platform. An authenticated user with limited privileges can exploit this vulnerability to inject malicious scripts that target other admin users, achieving privilege escalation from one admin user to another (admin-to-admin XSS attack). The vulnerability stems from insufficient sanitization in certain input fields that bypasses existing XSS filters.

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.
-
Check installed Magento versionRun `composer show magento/product-community-edition 2>/dev/null | grep version` or check the version file at `app/etc/app.xml` or in the admin panel under System > Tools > Web Setup Wizard > System UpgradeAffected if The installed version falls within any of these ranges: >= 2.1.0 and < 2.1.18, >= 2.2.0 and < 2.2.9, or >= 2.3.0 and < 2.3.2
-
Identify admin users with limited privilegesIn the admin panel, navigate to System > Permissions > All Users and review user accounts. Check which users have limited role assignments (non-full administrative roles)Affected if There exist admin users with restricted privileges who could potentially exploit this bypass against higher-privilege admin users
-
Review admin session and activity logsCheck admin action logs in the admin panel under Reports > Action Logs or review server access logs for unusual POST requests to admin endpoints containing script tagsAffected if Unusual or suspicious admin activity is observed, particularly involving users with limited privileges accessing areas that affect other admin users
-
Inspect admin role permissions configurationNavigate to System > Permissions > User Roles and examine the role resources assigned to limited-privilege roles, particularly those allowing content or user management capabilitiesAffected if Limited-privilege roles have permissions that could be leveraged to inject malicious scripts targeting other admin users
You are affected if your Magento 2 installation version is below 2.1.18, 2.2.9, or 2.3.2 AND you have admin users with limited privileges configured in your system.

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 data2.1.182.2.92.3.2
Apply the Magento security patches or upgrade to the fixed versions (2.1.18+, 2.2.9+, or 2.3.2+) to resolve the XSS bypass. Review admin user permissions and monitor for suspicious admin activity until the patch is applied.
