A flaw was found in Apache Tomcat. A local attacker can gain unauthorized access to Unix domain communication sockets due to a time-of-check to time-of-use (TOCTOU) race condition in the APR/Native connector. When the connector initializes a socket, a brief timing window exists before restrictive permissions are applied, allowing an unauthorized local user to connect to the socket and potentially intercept or manipulate local service communications.
tomcat: tomcat: Unauthorized socket access via TOCTOU race condition — rated Low by Red Hat. Released 2026-10-20.
