CVE-2025-54532 is a medium-severity vulnerability identified in JetBrains TeamCity, a widely used continuous integration and continuous deployment (CI/CD) server. The vulnerability is categorized under CWE-863, which pertains to improper access control. Specifically, in versions of TeamCity prior to 2025.07, an attacker with limited privileges (requiring some level of authentication but no user interaction) can exploit improper access control mechanisms related to snapshot dependencies to disclose build settings. Snapshot dependencies in TeamCity allow one build configuration to depend on the results of another, and the improper access control flaw enables unauthorized users to access sensitive build configuration details that should be restricted. The CVSS 3.1 base score is 4.3, reflecting a network attack vector with low complexity and requiring privileges but no user interaction. The impact is limited to confidentiality, with no direct effect on integrity or availability. No known exploits are currently reported in the wild, and no patches or mitigation links are provided in the source data, indicating that this is a recently disclosed vulnerability.

For European organizations, the disclosure of build settings can have several implications. Build configurations often contain sensitive information such as environment variables, build scripts, and references to internal repositories or credentials. Exposure of this data could facilitate further attacks, including supply chain compromises or unauthorized access to internal systems. Organizations relying on TeamCity for their software development lifecycle may face increased risk of intellectual property leakage or targeted attacks if adversaries leverage disclosed build details. While the vulnerability does not directly affect system integrity or availability, the confidentiality breach can undermine trust in the CI/CD pipeline and potentially expose sensitive operational details. This risk is particularly relevant for sectors with stringent data protection requirements such as finance, healthcare, and critical infrastructure within Europe.

To mitigate this vulnerability, European organizations should prioritize upgrading TeamCity installations to version 2025.07 or later where the access control issue is resolved. In the absence of an immediate patch, administrators should review and tighten access permissions related to build configurations and snapshot dependencies, ensuring that only authorized personnel have access to sensitive build data. Implementing strict role-based access control (RBAC) policies within TeamCity can limit exposure. Additionally, monitoring and auditing access logs for unusual activity around build configurations can help detect exploitation attempts. Organizations should also consider isolating their CI/CD infrastructure from broader network access to reduce exposure. Finally, educating development and operations teams about the sensitivity of build settings and enforcing secure credential management practices will further reduce risk.
