This flaw impacts all versions of the plugin up to and including 3.7.8. The vulnerability originates from insufficient input sanitization of the \u003ccode\u003emc_auth\u003c/code\u003e parameter and inadequate preparation of existing SQL queries. This allows unauthenticated attackers to append malicious SQL statements, enabling them to illicitly extract sensitive data from the underlying database. The vulnerability poses a significant risk to the confidentiality of information stored on affected WordPress sites. Attackers can leverage this to gain unauthorized access to user data, configuration details, and other proprietary information, leading to potential data breaches and compliance issues.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003e\u003cstrong\u003eInitial Access\u003c/strong\u003e: An unauthenticated attacker identifies a WordPress site running the vulnerable My Calendar plugin (version 3.7.8 or below).\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eReconnaissance\u003c/strong\u003e: The attacker analyzes HTTP requests related to the My Calendar plugin, specifically identifying the \u003ccode\u003emc_auth\u003c/code\u003e parameter.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003ePayload Crafting\u003c/strong\u003e: The attacker constructs a malicious time-based blind SQL Injection payload designed to interact with the database through the \u003ccode\u003emc_auth\u003c/code\u003e parameter.
