LightLLM up to 1.2.0 allows remote code execution

CVE-2026-103041 · published 19 days ago
Summary

The LightLLM software (versions through 1.2.0) runs a cache service that anyone on the network can reach. Because the service processes data without checking it, an attacker could send specially crafted information that makes the program run arbitrary commands with the same rights as the service. Protect yourself by updating to a newer version or disabling the cache service on public interfaces.
