CVE-2026-55242
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 · uneditedERPNext is a free and open source Enterprise Resource Planning tool. Prior to 15.111.0 and 16.22.0, an authenticated user with a standard operational role can trigger server-side template injection through a configuration field, resulting in unauthorized disclosure of data outside the user's normal permission scope. This issue is fixed in versions 15.111.0 and 16.22.0.
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 confidenceServer-side template injection (SSTI) vulnerability in ERPNext allows authenticated users with standard operational roles to inject malicious template code through a configuration field, bypassing permission boundaries to access data outside their authorized scope.

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 installed ERPNext versionRun `bench version` or check the instance info in the ERPNext admin interface to retrieve the current version numberAffected if The installed version is earlier than 15.111.0 or 16.22.0 (or if version cannot be determined but the instance predates those releases)
-
Locate the affected configuration fieldReview ERPNext system settings, app-specific configurations, or custom app config pages where template rendering may be enabled for standard usersAffected if A configuration field exists that accepts Jinja2 or similar template syntax and is accessible to standard operational roles (e.g., standard users, non-admin roles)
-
Verify role permissions on the configurationUse the ERPNext Role Permission Manager to check which roles have write access to the affected configuration field or pageAffected if Standard operational roles (such as Accounts User, Stock User, or similar) have write or create permissions on the vulnerable configuration field
-
Inspect for unauthorized data accessReview ERPNext audit logs, access logs, or document access records for unusual patterns where standard users accessed data outside their permitted doctypesAffected if Audit logs show standard users accessed documents, fields, or data outside their role-permitted scope, indicating the permission boundary was bypassed
The environment is affected if the ERPNext version is below 15.111.0 or 16.22.0 and a configuration field accessible to standard operational roles allows template code injection.

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.
dbcve · scopedUpgrade ERPNext to version 15.111.0 or 16.22.0 (or later) to patch the SSTI vulnerability in the configuration field.
ERPNext 15.111.0 (for v15.x) or 16.22.0 (for v16.x)
- 1. Backup your ERPNext database and application data before proceeding with any upgrade
- 2. Identify your current ERPNext version by running `bench version` in your ERPNext/Frappe environment
- 3. If running ERPNext version 15.x, upgrade to version 15.111.0 by running `bench switch-to-branch version-15` followed by `bench update --upgrade`
- 4. If running ERPNext version 16.x, upgrade to version 16.22.0 by running `bench switch-to-branch version-16` followed by `bench update --upgrade`
- 5. After upgrade completes, clear caches with `bench clear-cache` and `bench clear-website-cache`
- 6. Verify the fix by logging in as a standard operational role user and confirming the configuration field no longer allows template injection
- 7. Test that normal role-based permissions are still enforced correctly
