Windows ML CLI: CORS misconfig enables localhost RCE

Case Description: MSRC Notes: Attachments: 1 files attached 1 mp4 Summary: The vulnerability lies in the 'serve/cliapi.py' component of the 'winml-cli' project, which exposes all winml CLI commands over HTTP without authentication. Although it binds to localhost by default, it sets 'alloworigins'...

CVE-2026-68770

A flaw was found in sentence-transformers. A remote attacker could exploit a logic flaw to bypass a security control designed to prevent the execution of untrusted code. This vulnerability allows for arbitrary code execution when an application loads a model from a directory that has been...

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-2026-68770

The CVE affects the sentence-transformers library, where a logic flaw in the import_module_class helper (sentence_transformers/util/misc.py) adds an incorrect guard: os.path.exists(model_name_or_path) causes the trust_remote_code gate to pass whenever the provided path exists locally. This enable...
