What is CVE-2026-85668?
CVE-2026-85668 is a high-severity path traversal vulnerability in xorbitsai inference, published on 4 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Xinference (affected commit 4a94832, v3.x) contains an unauthenticated arbitrary-path file read vulnerability in the POST /v1/models/llm/auto-register endpoint, which accepts a caller-supplied model_path parameter without authentication or path confinement. The endpoint reads and parses config.json, tokenizer_config.json, and chat_template.jinja files at the supplied path and reflects the parsed content back to the caller, allowing an unauthenticated attacker to probe the server filesystem and extract content of files with those names in any directory.
Weakness: CWE-73
