CVE-2026-5474

A vulnerability was found in NASA cFS up to 7.0.0. This affects the function CFE_MSG_GetSize of the file apps/to_lab/fsw/src/to_lab_passthru_encode.c of the component CCSDS Packet Header Handler. Performing a manipulation results in heap-based buffer overflow. The attacker must have access to the local network to execute the attack. The project was informed of the problem early through an issue report but has not responded yet.
