THE Known Exploited Vulnerabilities (KEV) Catalog is maintained by CISA to assist organizations in managing cybersecurity vulnerabilities that are actively exploited. The catalog serves as a resource for prioritizing vulnerability management efforts. It includes details such as the CVE-2026-63077 vulnerability in JetBrains TeamCity, which allows unauthenticated remote code execution through deserialization of untrusted data.
Users are encouraged to apply mitigation strategies as provided by vendors and adhere to CISA's guidelines. The catalog is available in various formats, including CSV and JSON.
