CVE-2026-13361 is a remote code execution vulnerability in the SQL Interface component of IBM Informix Dynamic Server. The flaw is caused by an unchecked SQL Interface length field in the oninit sq_sgkprepare code path. An authenticated SQL Interface client can send a specially crafted request that triggers a stack-based buffer overflow, potentially allowing attacker-controlled execution within the context of the Informix server process. Affected versions include Informix Dynamic Server 12.10.x, 14.10, and 15.0.
