Directory Traversal

Overview diffusers is a State-of-the-art diffusion in PyTorch and JAX. Affected versions of this package are vulnerable to Directory Traversal via the getcheckpointshardfiles function. An attacker can access arbitrary files by providing crafted weightmap values containing directory traversal...

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...
