This flaw stems from inadequate file type validation within the \u003ccode\u003eSVGFile\u003c/code\u003e constructor, specifically due to an incorrect conditional check that bypasses necessary validation. This allows authenticated attackers, who possess Administrator-level privileges or higher, to upload arbitrary malicious files to the affected WordPress server. Successful exploitation of this vulnerability could lead to remote code execution, enabling attackers to take full control of the compromised website and potentially the underlying server infrastructure.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker obtains or possesses Administrator-level credentials for a WordPress instance running the vulnerable MapSVG plugin (versions up to and including 8.14.0).\u003c/li\u003e\n\u003cli\u003eThe attacker logs into the WordPress administrative interface using the compromised credentials.\u003c/li\u003e\n\u003cli\u003eLeveraging the vulnerable functionality of the MapSVG plugin, the attacker crafts and sends a request to upload a malicious file (e.g., a PHP web shell), exploiting the missing file type validation (CVE-2026-1771).\u003c/li\u003e\n\u003cli\u003eThe web server processes the upload, and due to the vulnerability, the malicious file is successfully stored on the server, typically within a publicly accessible directory associated with the MapSVG plugin.\u003c/li\u003e\n\u003cli\u003eThe attacker sends a subsequent HTTP GET request to the known or inferred URL of the newly uploaded malicious file (e.g., \u003ccode\u003ewp-content/plugins/mapsvg/uploads/shell.php\u003c/code\u003e).\u003c/li\u003e\n\u003cli\u003eThe web server executes the malicious script, granting the attacker remote code execution capabilities on the underlying system.\u003c/li\u003e\n\u003cli\u003eThe attacker uses the web shell to issue arbitrary commands, interact with the server's file system, exfiltrate sensitive data, or establish further persistence on the compromised server.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-1771 can grant attackers remote code execution capabilities on the affected WordPress server.
