SCA: security update for banks (GHSA-hmq2-7hp6-7crh)

medium Tenable Self-Hosted Container Security Plugin ID 473936

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Banks generates meaningful LLM prompts using a simple template language. Prior to 2.5.0, Banks
 Prompt.chat_messages() attempts to parse every line of rendered template output as ChatMessage JSON. When
 an application renders untrusted data and passes the returned ChatMessage objects to an LLM provider,
 attacker-controlled JSON can cross the prompt boundary and become a system, assistant, or tool message
 because ChatMessage.role accepts arbitrary strings. This can override application instructions, alter the
 intended prompt structure, or confuse downstream tool and message handling. This issue is fixed in version
 2.5.0. (CVE-2026-107717)

Solution

Update the banks library and its related packages to version 2.5.0 or later.
