CVE-2018-11127
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 · uneditede107 2.1.7 has CSRF resulting in arbitrary user deletion.
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 confidenceCSRF vulnerability in e107 2.1.7 allows authenticated administrators to be tricked into deleting arbitrary user accounts through malicious requests, as the application lacks proper anti-CSRF token validation on user deletion operations.

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 e107 installation versionLocate the version file or admin dashboard showing the e107 version. Check files like version.php or the admin area 'About' page that displays the software version.Affected if The installed version is exactly 2.1.7 or falls within the 2.1.7 release line
-
Verify administrator access to user managementLog into the e107 admin panel and navigate to the user management or users administration section. Confirm that deletion functionality for user accounts exists.Affected if The admin panel provides a user deletion feature and the administrator has access to it
-
Inspect user deletion code for CSRF token validationExamine the server-side code handling user deletion requests (typically in the users admin controller or handler files). Check whether the deletion action validates a CSRF token or anti-CSRF mechanism before processing the request.Affected if The user deletion handler does not validate or require a CSRF token (synchronizer token pattern) before executing the deletion
-
Check cookie configuration for SameSite attributeInspect the application's cookie settings or configuration files. Look at how session and authentication cookies are defined and whether they include the SameSite attribute.Affected if Cookies related to admin authentication do not have the SameSite attribute configured, or SameSite is set to None/Lax without secure flags
The environment is affected if running e107 version 2.1.7 with an authenticated administrator able to access user deletion functionality that lacks CSRF token validation on deletion requests.

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 dataImplement anti-CSRF tokens (synchronizer token pattern) on all state-changing operations including user management functions, and configure SameSite cookies to provide additional protection against CSRF attacks.
