Product: Dot

Description

The desktop application in Dot through 0.9.3 allows XSS and resultant command execution because user input and LLM output are appended to the DOM with innerHTML (in render.js), and because the Electron window can access Node.js APIs.

Technical Analysis

CVE-2024-57783 is a high-severity vulnerability affecting the desktop application 'Dot' developed by alexpinel, specifically versions up to 0.9.3. The vulnerability is categorized under CWE-79, which corresponds to improper neutralization of input during web page generation, commonly known as Cross-site Scripting (XSS). In this case, the vulnerability arises because both user input and outputs from a large language model (LLM) are appended directly to the Document Object Model (DOM) using the innerHTML property in the render.js file. This practice allows maliciously crafted input to inject executable scripts into the application’s interface. Since Dot is built on Electron, which combines Chromium and Node.js, the Electron window has access to Node.js APIs. This means that successful exploitation of the XSS vulnerability can lead to command execution on the underlying system, significantly elevating the risk beyond typical browser-based XSS attacks. The CVSS v3.1 base score is 8.1, reflecting high severity with a vector indicating local attack vector (AV:L), high attack complexity (AC:H), no privileges required (PR:N), no user interaction (UI:N), and a scope change (S:C) that affects confidentiality, integrity, and availability (all rated high). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was reserved in early 2025 and published in June 2025, indicating recent discovery and disclosure.

Potential Impact

For European organizations using the Dot desktop application, this vulnerability poses a significant risk. The ability to execute arbitrary commands through XSS can lead to full system compromise, data theft, unauthorized access to sensitive information, and disruption of services. Since Electron applications typically have access to local file systems and system resources, attackers exploiting this vulnerability could install malware, exfiltrate data, or pivot within internal networks. The high severity and scope change imply that the impact extends beyond the application itself to the host system and potentially connected infrastructure. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, could face regulatory penalties if breaches occur. Additionally, the lack of required privileges and user interaction lowers the barrier for exploitation, increasing the threat level. The absence of known exploits suggests that proactive mitigation is critical to prevent future attacks.

Mitigation Recommendations

Given the nature of the vulnerability, European organizations should take immediate and specific actions: 1) Avoid using versions of Dot up to 0.9.3 until a patch is released. 2) If usage is unavoidable, restrict the application’s access using OS-level sandboxing or application whitelisting to limit potential damage from exploitation. 3) Monitor application behavior and system logs for unusual activity indicative of exploitation attempts. 4) Implement strict input validation and sanitization in any custom integrations or scripts interacting with Dot, especially if user input or LLM outputs are involved. 5) Engage with the vendor or community to obtain or contribute to patches that replace innerHTML usage with safer DOM manipulation methods, such as textContent or proper sanitization libraries. 6) Educate users about the risks of running untrusted content within the application. 7) Consider network segmentation to isolate systems running Dot from critical infrastructure. These steps go beyond generic advice by focusing on containment, monitoring, and proactive code hygiene specific to Electron-based XSS risks.
