Privilege Escalation Vulnerability in JetBrains TeamCity

CVE-2025-54530

What is CVE-2025-54530?

CVE-2025-54530 is a privilege escalation vulnerability in JetBrains TeamCity, a widely used continuous integration and continuous delivery (CI/CD) server that automates the development process. This vulnerability stems from incorrect directory permissions in versions prior to 2025.07, allowing users to potentially elevate their access rights within the system. If exploited, this vulnerability can enable unauthorized users to perform actions that should be restricted, potentially compromising sensitive project data and configurations. Organizations relying on TeamCity for managing their build and deployment processes are at risk of having their internal workflows disrupted or manipulated.

Potential Impact of CVE-2025-54530

1. Unauthorized Access: The vulnerability allows users with lower privilege levels to escalate their access, potentially enabling them to manipulate build processes, view sensitive information, or make unauthorized changes to project configurations.

2. Data Breaches: With elevated privileges, an attacker could access confidential source code, credentials, and other sensitive data, leading to potential data leaks or breaches.

3. Disruption of Services: Exploitation of this vulnerability could result in significant disruptions to the CI/CD workflows, affecting development teams' productivity and leading to financial losses due to downtime or compromised integrity of software releases.
