CVE-2026-5220
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 · uneditedImproper neutralization of input during web page generation ('cross-site scripting') vulnerability in DivvyDrive Information Technologies Inc. DivvyDrive allows Stored XSS. This issue affects DivvyDrive: from 4.8.2.23 before v.4.8.3.1.
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 exists in DivvyDrive versions 4.8.2.23 through before 4.8.3.1. The vulnerability allows attackers to inject malicious JavaScript code into the application, which is then stored and executed 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.
-
Confirm DivvyDrive is deployedIdentify whether DivvyDrive file sync and sharing software is installed in your environment. Check for DivvyDrive processes, services, or installed directories.Affected if DivvyDrive is present in the environment
-
Check installed version numberLocate the version information for your DivvyDrive installation (typically found in the application UI under About/Help, or in installation logs, registry, or config files). Compare your version against the affected range: 4.8.2.23 through versions before 4.8.3.1.Affected if Installed version is 4.8.2.23 or higher but lower than 4.8.3.1
-
Identify user input entry pointsReview the DivvyDrive application to determine which fields accept user-supplied content that gets stored and displayed to other users (such as file names, descriptions, comments, or metadata fields).Affected if User input fields exist that store and display content to other users
-
Review application logs for XSS indicatorsExamine DivvyDrive server or application logs for patterns matching script tags, javascript: URIs, or other XSS payload signatures in user-submitted data fields.Affected if Logs contain suspicious script injection patterns in user input fields
You are affected if DivvyDrive is installed with a version between 4.8.2.23 and 4.8.3.0 inclusive and exposes user input fields that store content for other users to view.
Generated from the published advisory. Verify against your own configuration.
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 DivvyDrive to version 4.8.3.1 or later. Until patched, restrict user input handling and monitor for malicious script injection attempts in user-supplied data fields.
DivvyDrive v.4.8.3.1
- 1. Create a complete backup of the current DivvyDrive installation and database
- 2. Download DivvyDrive version 4.8.3.1 from the official DivvyDrive Information Technologies Inc. vendor source
- 3. Review vendor upgrade documentation for version 4.8.3.1
- 4. Apply the upgrade to the DivvyDrive instance
- 5. After upgrade, verify that the XSS vulnerability is resolved by testing input fields that previously allowed stored XSS
- 6. Confirm normal application functionality post-upgrade
