AI-suggested
To mitigate this vulnerability, European organizations should: 1) Immediately upgrade JetBrains TeamCity to version 2025.07.1 or later once available, as this version addresses the SMTP injection flaw. 2) Restrict high-privilege access to TeamCity to only trusted administrators and enforce strong authentication mechanisms such as multi-factor authentication (MFA). 3) Audit and monitor email notification configurations and logs for unusual or unauthorized changes in email content or recipients. 4) Implement network segmentation to limit access to the TeamCity server and its SMTP services, reducing exposure to potential attackers. 5) Educate development and operations teams about the risks of phishing and social engineering attacks that could arise from manipulated CI/CD notifications. 6) Consider deploying email security solutions that can detect and block suspicious or malformed emails originating from internal systems. 7) Regularly review and update security policies related to CI/CD tools and their integrations to ensure timely patching and vulnerability management.
