Vulnerability from github – Published: 2026-04-22 15:31 – Updated: 2026-04-22 15:31

Details

A flaw was found in InstructLab. A local attacker could exploit a path traversal vulnerability in the chat session handler by manipulating the logs_dir parameter. This allows the attacker to create new directories and write files to arbitrary locations on the system, potentially leading to unauthorized data modification or disclosure.

Severity ?

7.1 (High)
