Vulnerability from github – Published: 2026-09-14 09:31 – Updated: 2026-09-14 09:31

Details

A weakness has been identified in 0x4m4 HexStrike AI up to d689933ff579d839c676c82b231f8e98326c5f04. The affected element is the function subprocess.Popen of the file hexstrike_server.py of the component API Tools Endpoint. Executing a manipulation of the argument additional_args/target/username/password/scan_type/payload can lead to os command injection. The attack can be launched remotely. The exploit has been made available to the public and could be used for attacks. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. A fix appears to be in progress.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
