CVE-2026-65920

A flaw was found in Diffusers. This path traversal vulnerability in the getcheckpointshardfiles function allows a remote attacker to read arbitrary files. By supplying malicious weightmap values in model index JSON, an attacker can use ../ sequences or absolute paths to escape the model directory...

CVE-2026-65920

Diffusers through 0.39.0, fixed in commit cee298c, contains a path traversal vulnerability in the getcheckpointshardfiles function that allows attackers to read arbitrary files by supplying malicious weightmap values in model index JSON. Attackers can use ../ sequences or absolute paths in...

CVE-2026-65920

Diffusers up to 0.39.0 is affected by a path traversal in the _get_checkpoint_shard_files function. Attackers can supply malicious weight_map values in the model index JSON (e.g., ../ sequences or absolute paths) to escape the model directory and read safetensors files outside the intended locati...

CVE-2026-45804

Diffusers CVE-2026-45804 describes a TOCTOU race in DiffusionPipeline.from_pretrained where two Hub fetches (config via hf_hub_download and a snapshot via snapshot_download) can resolve to different commits. An attacker could push commit B after the first check, causing the newer commit’s model_i...

CVE-2026-44513

A flaw was found in Diffusers, a library for pretrained diffusion models. A remote attacker could exploit a bypass in the trustremotecode mechanism within the DiffusionPipeline.frompretrained function. This vulnerability allows for arbitrary remote code execution, even when the user explicitly se...

CVE-2026-44827

Diffusers is the a library for pretrained diffusion models. Prior to 0.38.0, diffusers 0.37.0 allows remote code execution without the trustremotecode=True safeguard when loading pipelines from Hugging Face Hub repositories. The resolvecustompipelineandcls function in pipelineloadingutils.py...

Time-of-check Time-of-use (TOCTOU) Race Condition

Overview diffusers is a State-of-the-art diffusion in PyTorch and JAX. Affected versions of this package are vulnerable to Time-of-check Time-of-use TOCTOU Race Condition in the frompretrained flow. An attacker can execute arbitrary code by exploiting a race condition between two repository fetch...
