CVE-2026-22600 Details
Description
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.
A local file read vulnerability has been identified in OpenProject versions prior to 16.6.4. This issue arises in the work package PDF export feature, where a specially crafted SVG file, disguised as a PNG, can be uploaded as an attachment. Exploiting this vulnerability involves triggering the backend image processing engine, ImageMagick, which then reads arbitrary local files accessible to the application user, such as system files and project data. The vulnerability requires permission to upload attachments to a container that can be exported to PDF, like a work package.
Users can upgrade to OpenProject version 16.6.4 or apply the available patch manually. If immediate upgrading is not possible, as a temporary measure, PDF export permissions can be removed from users.
