CVE-2025-28892
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 · uneditedCross-Site Request Forgery (CSRF) vulnerability in a2rocklobster FTP Sync ftp-sync allows Stored XSS.This issue affects FTP Sync: from n/a through <= 1.1.6.
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 confidenceCross-Site Request Forgery (CSRF) vulnerability in FTP Sync <= 1.1.6 allows attackers to craft malicious requests that result in Stored XSS, enabling arbitrary script execution in user browsers when the crafted payload is rendered.

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 FTP Sync installation and versionLocate the FTP Sync application in your environment and determine its installed version number. Check plugin directories, application manifests, or version files typically found in the plugin root or admin interface.Affected if The installed version is 1.1.6 or lower.
-
Confirm application handles stored dataExamine FTP Sync to verify it stores and displays data that could contain user-supplied content, such as sync profiles, server configurations, or file lists that are rendered back to users.Affected if The application stores and renders user-accessible data without immediate encoding.
-
Inspect state-changing operations for CSRF protectionReview the application's source code or network requests for state-changing actions (such as saving sync profiles, modifying server settings, or triggering sync operations) to determine if anti-CSRF tokens or unique request identifiers are required.Affected if State-changing operations lack CSRF token validation or origin verification.
-
Check stored data output encodingExamine how stored data (especially data that could be user-supplied) is rendered in the application interface to verify if proper output encoding or input sanitization is applied before rendering.Affected if Stored data is rendered without sanitization or encoding, allowing script injection.
You are affected if FTP Sync version 1.1.6 or lower is installed and the application stores and displays data without CSRF protection on state-changing operations and without proper output encoding.

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 for state-changing operations and apply proper input sanitization/output encoding to prevent XSS injection and execution.
