CVE-2020-4066 (GCVE-0-2020-4066)

Vulnerability from cvelistv5 – Published: 2020-06-22 15:25 – Updated: 2024-08-04 07:52

Title

Command Injection in Limdu trainBatch function

Summary

In Limdu before 0.95, the trainBatch function has a command injection vulnerability. Clients of the Limdu library are unlikely to be aware of this, so they might unwittingly write code that contains a vulnerability. This has been patched in 0.95.

Severity

3.8 (Low)
