Hugging Face Diffusers Flaws Could Let Model Repositories Execute Arbitrary Code
Three high-severity security flaws have been disclosed in Hugging Face's Diffusers library that could allow crafted model repositories to stealthily execute arbitrary code on machines that load it, opening the artificial intelligence AI supply chain to security risk. "These vulnerabilities are...
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
A flaw was found in Diffusers, a library for pretrained diffusion models. A remote attacker could exploit this vulnerability by crafting a malicious Hub repository with custom Python pipeline code. The DiffusionPipeline.frompretrained flow can bypass the trustremotecode security mechanism, allowi...
CVE-2026-45804
Diffusers is the a library for pretrained diffusion models. Prior to 0.38.0, Diffusers' DiffusionPipeline.frompretrained flow can bypass the trustremotecode guard because download validates modelindex.json and custom pipeline code before later loading from a cached folder that can change, allowin...

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...
