Overview

CVE-2026-28274 is a high-severity vulnerability. It was published on February 26, 2026 and has a CVSS 3.1 base score of 8.7 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.7, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

Initiative is a self-hosted project management platform. Versions of the application prior to 0.32.4 are vulnerable to Stored Cross-Site Scripting (XSS) in the document upload functionality. Any user with upload permissions within the "Initiatives" section can upload a malicious `.html` or `.htm` file as a document. Because the uploaded HTML file is served under the application's origin without proper sandboxing, the embedded JavaScript executes in the context of the application. As a result, authentication tokens, session cookies, or other sensitive data can be exfiltrated to an attacker-controlled server. Additionally, since the uploaded file is hosted under the application's domain, simply sharing the direct file link may result in execution of the malicious script when accessed. Version 0.32.4 fixes the issue.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
