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.

The injected script executes in the browsers of other users viewing the comment, potentially leading to session hijacking or credential theft.

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.
-

-
Verify the exact version numberAccess the admin dashboard, navigate to the About or Help section, and record the displayed version numberAffected if The version shows exactly 13.0 (no patches or hotfixes applied)
-
Confirm the status comment feature is accessibleLog into ServiceDesk Plus as a user with permission to view or add status comments on requests, navigate to any request details page, and locate the comment/status fieldAffected if The comment field is present and accessible without additional configuration changes
-

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 input validation and output encoding on the comment field to sanitize user-supplied content; apply context-aware escaping before rendering comments in the browser. Consider deploying a web application firewall as an additional layer of defense.
