CVE-2026-66030 - Ekushey Project Manager CRM 5.0 Stored XSS via Client Name Field

A GitHub repository version of this disclosure can be read here: CVE-2026-66030.

Description

Ekushey Project Manager CRM through version 5.0 contains a stored cross-site scripting vulnerability that allows authenticated client users to inject arbitrary HTML and JavaScript by entering malicious payloads into the Ticket Title field on the Create New Ticket page. Attackers can craft and store malicious scripts that execute in the browser sessions of Staff or Administrator users who view the Client Support page where ticket titles are rendered unsanitized.

Proof-of-Concept

1. Only the Client users are able to create new tickets. Authenticate as a lower-privileged Client user, navigate to the Create New Ticket page, and set the Ticket Title field to the following XSS payload. Fill in any required remaining fields with valid data and submit the form:

<u>Ticket Title</u><script>alert("Client Name Stored XSS")</script>

2. Log out of the Client account and log in as a Staff user. Navigate to All Support Tickets in the left panel. The payload executes immediately upon rendering the ticket summary table.

3. Authenticate as an Admin user and navigate to the Client Support page. The stored XSS triggers identically within the Admin control panel.
