Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-791: Incomplete Filtering of Special Elements, where the product receives data from an upstream component, but does not completely filter special elements before sending it to a downstream component. In AstrBot, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A security flaw has been discovered in AstrBotDevs AstrBot up to 4.22.1. This affects the function create_template of the file astrbot/dashboard/routes/t2i.py of the component Dashboard API. The manipulation results in improper neutralization of special elements used in a template engine. The attack can be executed remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
