4ga Boards Path Traversal Vulnerability Exposes Local Files (CVE-2026-41419)
A path traversal vulnerability, tracked as CVE-2026-41419, has been identified in 4ga Boards, a project management system. The National Vulnerability Database reports that prior to version 3.3.5, an authenticated user with board import privileges can exploit this flaw. The vulnerability allows the server to ingest arbitrary host files as board attachments during the import of BOARDS archives.
Once imported, these files become accessible for download through the application’s normal interface, leading to unauthorized local file disclosure. The National Vulnerability Database assigns this a CVSS score of 7.6 (High severity), emphasizing the significant risk of sensitive data exposure. The issue is remediated in 4ga Boards version 3.3.5.
This isn’t just a theoretical flaw; it’s a direct route to sensitive data. Attackers, once authenticated and with the right privileges, can exfiltrate configuration files, private keys, or other critical system data that defenders assume is air-gapped from application-level access. The attacker’s calculus is simple: gain a foothold, then leverage this to expand access and extract high-value information.
What This Means For You
- If your organization uses 4ga Boards, check your deployed version immediately. Prioritize upgrading to version 3.3.5 or later to mitigate CVE-2026-41419. Audit logs for any suspicious board import activities by privileged users, as this could indicate attempts at local file disclosure.
