CVE-2026-46517: LMDeploy: Hardcoded trust_remote_code=True is an implicit unsafe remote-code load path with no user opt-out

HighCVSS 7.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.16% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: lmdeploy (PyPI) 0.13.0.

Low priority for now. Upgrade to lmdeploy (PyPI) 0.13.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

LMDeploy is a toolkit for compressing, deploying, and serving large language models. In versions 0.12.3 and prior, hardcoded "trust_remote_code=True" enables HF supply-chain RCE without user opt-in. Version 0.13.0 patches the issue.
