CVE-2022-46825 is a medium-severity information disclosure vulnerability identified in JetBrains IntelliJ IDEA versions prior to 2022.3. The vulnerability arises from the built-in web server component of IntelliJ IDEA, which inadvertently leaks information about open projects. Specifically, this vulnerability is categorized under CWE-200, which pertains to the exposure of sensitive information to unauthorized actors. The built-in web server is designed to facilitate certain development workflows, such as previewing web content or enabling remote access features. However, due to insufficient access controls or improper handling of requests, it can reveal metadata or details about the projects currently open in the IDE. This information leakage could include project names, directory structures, or other contextual data that may aid an attacker in reconnaissance activities. Although no known exploits are currently reported in the wild, the presence of this vulnerability could allow an attacker with network access to the affected system to gather intelligence that may be leveraged for further targeted attacks. The vulnerability does not appear to require authentication or user interaction, increasing the risk in environments where the built-in web server is exposed beyond trusted networks. JetBrains has acknowledged the issue, but no specific patch links are provided in the available data, indicating that users should upgrade to version 2022.3 or later where the issue is resolved.

For European organizations, the impact of CVE-2022-46825 primarily revolves around the confidentiality of development environments. Leakage of open project information can expose sensitive intellectual property, internal project structures, or development priorities. This could facilitate targeted attacks such as spear-phishing, social engineering, or exploitation of known vulnerabilities in disclosed projects. Organizations involved in software development, especially those handling proprietary or sensitive projects (e.g., financial services, defense contractors, or critical infrastructure providers), may face increased risk of espionage or competitive disadvantage. While the vulnerability does not directly compromise system integrity or availability, the information disclosure can be a stepping stone for more severe attacks. Given the collaborative nature of software development and the potential exposure of internal project details, the vulnerability could also impact supply chain security if attackers gain insights into third-party dependencies or development processes. The absence of known exploits reduces immediate risk, but the medium severity rating and ease of information gathering warrant prompt attention.

To mitigate the risk posed by CVE-2022-46825, European organizations should implement the following specific measures: 1) Upgrade IntelliJ IDEA installations to version 2022.3 or later, where the vulnerability has been addressed. 2) Restrict network access to the built-in web server by configuring firewalls or network segmentation to limit exposure only to trusted hosts and internal networks. 3) Disable the built-in web server if it is not required for development workflows, thereby eliminating the attack surface. 4) Monitor network traffic for unusual access attempts to the web server port, which could indicate reconnaissance activity. 5) Educate developers and IT staff about the risks of exposing development tools to untrusted networks and enforce secure configuration baselines. 6) Implement endpoint security controls to detect and prevent unauthorized access attempts to development environments. 7) Review and audit project metadata and configuration files to ensure no sensitive information is inadvertently exposed through other means. These targeted actions go beyond generic patching advice by focusing on network controls, operational practices, and awareness tailored to the nature of the vulnerability.
