Hash collision weakness in PaddlePaddle FastDeploy up to version 2.4.1 allows a local attacker with low privileges to cause the MultimodalHasher component to produce identical SHA-256 digests for semantically distinct numpy arrays that share raw byte content but differ in shape or dtype. This breaks the uniqueness guarantee of the hash_features function in fastdeploy/multimodal/hasher.py, enabling integrity violations in multimodal data pipelines relying on this component for deduplication or identity checks. No public exploit exists and no active exploitation is confirmed; the CVSS 4.0 score of 2.0 accurately reflects constrained real-world risk given local-only access and high attack complexity.
