CVE-2026-6984: Medium Vulnerability in AstrBotDevs AstrBot

A security flaw has been discovered in AstrBotDevs AstrBot up to 4.22.1. This vulnerability allows attackers to manipulate the function create_template of the file astrbot/dashboard/routes/t2i.py within the Dashboard API component. The vulnerability results in improper neutralization of special elements used in a template engine. Thus, the attack can be executed remotely.

With a CVSS score of 5.1, the severity of this vulnerability is classified as medium, indicating a notable risk to organizations using affected versions of AstrBot. 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.

Organizations should prioritize patching immediately to mitigate potential risks associated with this vulnerability. The risk to organizations includes unauthorized access and manipulation of the system, which may lead to further exploitation if not addressed promptly.

Defenders should be aware of the current exploitation status and the availability of a patch, as the vulnerability has been acknowledged, but details on remediation are yet to be disclosed.

Vulnerability Details

This vulnerability affects AstrBotDevs AstrBot versions up to 4.22.1. The flaw resides in the create_template function of the Dashboard API component. It is classified under CWE-791 (Improper Control of Generation of Code ('Code Injection')) and CWE-1336 (Improper Neutralization of Special Elements used in an Expression Language).

The CVSS score of 5.1 indicates a medium severity level, which signifies that there is a moderate risk of exploitation. The vulnerability is exploitable over the network with low attack complexity and requires high privileges, suggesting that an attacker would need certain access rights to exploit the flaw.

The vulnerability was published on April 25, 2026, and has not yet been scored by CVSS 3.1. The lack of a public exploit confirms that there is an urgent need for remediation to prevent potential unauthorized access.

Technical Analysis

The root cause of this vulnerability lies in the improper handling and neutralization of special elements in the template engine, which can be exploited through remote code execution. The attack vector is network-based, with low complexity involved in executing the attack.

Attackers require high privileges to exploit this vulnerability, indicating that it is likely targeting users with elevated access rights. Moreover, user interaction is not required to successfully carry out the attack.

The impact of the vulnerability is classified as low for confidentiality, integrity, and availability, but the potential for exploitation remains a concern. It is vital for organizations to understand that although the impact may be low, the exploitation can lead to unauthorized access and manipulation of sensitive data.

Risk & Impact Analysis

Organizations using versions of AstrBotDevs AstrBot up to 4.22.1 face a medium risk of exploitation due to this vulnerability. The potential blast radius includes unauthorized access and manipulation of the system, which can lead to significant operational disruptions.

Given the current status of the vulnerability, which has been confirmed and publicized, it should be prioritized for remediation. The CVSS score of 5.1 indicates a medium urgency for patching, and organizations should address this in their priority patch cycle.

Security teams should be vigilant and monitor the situation as further details on exploitation may emerge. The urgency for organizations to act cannot be overstated, as the longer the delay, the greater the risk of successful exploitation.
