CVE-2026-92153 Details
Description
F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.3.0, Svc::FileUplink handling of Fw::FilePacket::StartPacket destination paths FileUplink copies the packet-controlled destinationPath and opens it for writing without canonicalization or confinement to an upload directory. When a peer able to send file-uplink packets supplies an absolute, traversing, or otherwise attacker-selected writable destination path, files can be created or overwritten at attacker-selected writable filesystem locations, affecting integrity and potentially availability. This issue is fixed in version 4.3.0.
A vulnerability in the F Prime framework's file uplink service allows for arbitrary file creation and overwriting at attacker-chosen locations on the filesystem. This issue arises because the service does not properly validate or restrict destination paths before writing files. The vulnerability is present in all versions prior to 4.3.0.
Users are advised to update to F Prime version 4.3.0 or later, where this vulnerability has been fixed. In addition, when configuring the file uplink service, it is recommended to specify a sandbox directory that restricts file writes to safe locations.
