Description
A security flaw has been discovered in NousResearch hermes-agent 0.8.0. This affects the function _check_sensitive_path of the file tools/file_tools.py. The manipulation results in symlink following. Attacking locally is a requirement. The exploit has been released to the public and may be used for attacks. Upgrading to version 0.9.0 is able to mitigate this issue. The patch is identified as 311dac197145e19e07df68feba2cd55d896a3cd1. Upgrading the affected component is recommended.
