Discovery of XSS in AI Chat Feature

In the rapidly evolving digital era, cyber security has become one of the most paramount concerns. Threats to security no longer only arise from external attacks, but also from vulnerabilities within the software and platforms we use every day. This article delves into the discovery of a Cross-Site Scripting (XSS) vulnerability that I found within the Chat AI feature of an Indonesian community company.

Note: This article will refer to an Indonesian community company, but without explicitly mentioning the name due to permission limitations.

The Genesis of Discovery

The discovery of this XSS vulnerability began with curiosity and idle amusement, unexpectedly leading to a significant impact on a platform's security. I, who shall remain unnamed to protect privacy and permission constraints, started exploring various features on the [redacted] website. Amidst this exploration, I stumbled upon an intriguing feature that allowed users to create threads. This feature was accompanied by a Chat AI capable of automatically generating titles and descriptions.

Injecting XSS Payload

Intrigued by this feature, I decided to put it to the test. However, in this testing phase, I did not merely examine the primary function of the feature; I also began probing for potential vulnerabilities that malicious entities could exploit. During this experiment, I input an XSS payload

<a href="javascript:alert(1)">xss</a>

into the Chat AI form used to automatically generate descriptions.

To my surprise, the XSS payload successfully executed, and a popup appeared on the screen! The initial conclusion drawn from this experiment was that the platform was susceptible to XSS attacks, which could pave the way for more destructive attacks in the future.

The Significance of Security in the Digital Era

This incident underscores the critical importance of digital security in today's platforms. Vulnerabilities like XSS can be utilized by attackers to steal sensitive information, manipulate the appearance of web pages, or even compromise user accounts. Security is not the responsibility of a single party but a collaborative effort among developers, users, and security researchers. This discovery serves as a reminder that digital platforms must be diligently safeguarded to ensure safe and comfortable usage.

Report Vulnerability

Following the identification of this XSS vulnerability, I reached out to the [redacted] development team to report my findings. Although the company's name is not disclosed in this article for privacy reasons, collaboration between security researchers and development teams is of paramount importance. In many cases, honest security researchers who assist in identifying and rectifying vulnerabilities may receive monetary rewards or recognition for their contributions towards enhancing platform security.


My curiosity and idleness led to a profound impact on the realm of digital security. The discovery of an XSS vulnerability within the Chat AI feature of [redacted] serves as a testament to the non-negotiable significance of digital security. In an era where our reliance on technology is growing, upholding security within digital platforms is a collective responsibility. Collaborative efforts between security researchers and developers are crucial steps in maintaining user security and comfort in our ever-evolving digital world.
