This vulnerability, identified as CVE-2026-34220, stems from insufficient validation of user-supplied input when constructing database queries. Specifically, specially crafted objects can be misinterpreted as raw SQL fragments, leading to unintended code execution. The attack surface lies in ORM write APIs, particularly those that directly process user-provided data without proper sanitization. Defenders should prioritize patching or implementing input validation to mitigate this risk. This vulnerability can lead to data breaches, unauthorized data modification, or complete database compromise.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker identifies an application using a vulnerable version of MikroORM (\u0026lt;= 6.6.9 or \u0026lt;= 7.0.5).\u003c/li\u003e\n\u003cli\u003eThe attacker locates an API endpoint that utilizes one of the vulnerable MikroORM methods: \u003ccode\u003ewrap(entity).assign(userInput)\u003c/code\u003e, \u003ccode\u003eem.nativeUpdate()\u003c/code\u003e, \u003ccode\u003eem.nativeInsert()\u003c/code\u003e, or \u003ccode\u003eem.create()\u003c/code\u003e.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious object containing SQL injection payloads designed to exploit the lack of input validation.
