The vulnerability allows unauthenticated attackers to inject arbitrary SQL code by manipulating the 'id' parameter within POST requests. Successful exploitation can lead to the extraction of sensitive information from the database or complete compromise of the vulnerable application. This vulnerability was disclosed in March 2026 and poses a significant risk to organizations using affected versions of SAT CFDI. Due to the sensitive nature of the data handled by CFDI systems, organizations should prioritize patching or mitigating this vulnerability.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker identifies a vulnerable SAT CFDI 3.3 instance.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious POST request targeting the \u003ccode\u003e/signIn\u003c/code\u003e endpoint.\u003c/li\u003e\n\u003cli\u003eThe attacker injects SQL code into the \u003ccode\u003eid\u003c/code\u003e parameter of the POST request.
