CVE-2026-22600 - Openproject Plugin
CVE-2026-22600
OpenProject is an open-source, web-based project management software. A Local File Read (LFR) vulnerability exists in the work package PDF export functionality of OpenProject prior to version 16.6.4. By uploading a specially crafted SVG file (disguised as a PNG) as a work package attachment, an attacker can exploit the backend image processing engine (ImageMagick). When the work package is exported to PDF, the backend attempts to resize the image, triggering the ImageMagick text: coder. This allows an attacker to read arbitrary local files that the application user has permissions to access (e.g., /etc/passwd, all project configuration files, private project data, etc.). The attack requires permissions to upload attachments to a container that can be exported to PDF, such as a work package. The issue has been patched in version 16.6.4. Those who are unable to upgrade may apply the patch manually.

Potential Impact
Severity is CRITICAL (CVSS 9.1). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.
Exploitability Assessment
Exploitability is assessed as High based on published exploit references, remote code execution potential.
Primary risk drivers: published exploit references, remote code execution potential
Mitigation Recommendations
Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.
Detection & Monitoring
Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.
Business Impact Lens
Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.
