CVE-2026-66029 - Ekushey Project Manager CRM 5.0 Stored XSS via Client Name Field

A GitHub repository version of this disclosure can be read here: CVE-2026-66029.

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 client Name field on the Edit Profile page without sanitization. Attackers can craft and store malicious scripts that execute in the browser sessions of Staff or Administrator users who view the Manage Clients or Manage Client Projects pages where client names are rendered unsanitized.

Proof-of-Concept

1. Authenticate as a lower-privileged Client user, navigate to the Edit Profile page, and update the Name field with the following XSS payload:

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

2. Log out of the Client account and log in as a Staff user. Navigate to either Manage Clients or Manage Client Projects. The payload executes immediately upon rendering the client list or project table.

3. Authenticate as an Admin user and navigate to the Client Projects page. The stored XSS triggers identically in the Admin panel.
