CVE-2026-72529 is a missing-authentication vulnerability in an undocumented TrueConf Server function reachable over TCP port 4307. An unauthenticated remote attacker can invoke the function to execute arbitrary scripts within an isolated environment. Vulnerable releases include the 5.3, 5.4, and 5.5 branches and earlier versions. The vulnerability has been actively exploited by Head Mare, including in a chain with CVE-2026-72530 to escape isolation and execute code on the underlying host.
