Hackers Start Exploiting Recent JetBrains TeamCity Vulnerability

A critical, unauthenticated remote code execution vulnerability in JetBrains TeamCity (CVE-2026-63077) is now being actively exploited by threat actors in the wild. The flaw requires no prior authentication to trigger, making it accessible to any attacker with network access to an affected instance.

Why it matters: Organizations running TeamCity must immediately apply patches or implement network controls, as attackers are already weaponizing this vulnerability to gain code execution on their servers.
