CVE-2026-61536
Description
A flaw was found in Banks, a tool for generating LLM prompts. This vulnerability allows a remote attacker to achieve arbitrary code execution by injecting a malicious tool definition into a template. The system improperly resolves the path specified in this definition, enabling the attacker to import and run unauthorized code within the Banks application.
Statement
This is an Important arbitrary code execution vulnerability in the 'banks' component, affecting Red Hat products that utilize it for LLM prompt generation. The flaw allows an attacker to execute arbitrary Python code by injecting malicious tool definitions into rendered templates, leveraging unsanitized 'import_path' fields. This bypasses existing sandboxing mechanisms, as the malicious content is processed directly from the template body.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
