The vulnerability stems from the CV upload handler\u0026rsquo;s failure to adequately validate file types. This oversight allows unauthenticated attackers to upload malicious files, including those with executable extensions, directly to the web server. Successful exploitation can result in remote code execution, enabling attackers to compromise the affected WordPress installation and potentially gain full control of the underlying server. This vulnerability poses a significant risk to websites utilizing the Career Section plugin, as it can lead to data breaches, website defacement, or use of the compromised server for malicious activities.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn unauthenticated attacker identifies a WordPress site using the vulnerable Career Section plugin (versions \u0026lt;= 1.7).\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious file, such as a PHP script disguised as a CV, designed to execute arbitrary code on the server.\u003c/li\u003e\n\u003cli\u003eThe attacker leverages the CV upload handler in the Career Section plugin to upload the malicious file, exploiting the lack of file type validation.\u003c/li\u003e\n\u003cli\u003eThe attacker navigates to the uploaded file\u0026rsquo;s location on the server, triggering its execution.\u003c/li\u003e\n\u003cli\u003eThe malicious file executes code, granting the attacker initial access to the server.\u003c/li\u003e\n\u003cli\u003eThe attacker escalates privileges (if necessary) to gain higher-level control of the system.\u003c/li\u003e\n\u003cli\u003eThe attacker installs a web shell or other persistent backdoor for continued access.\u003c/li\u003e\n\u003cli\u003eThe attacker performs malicious actions such as data exfiltration, website defacement, or further lateral movement within the network.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-6271 can lead to complete compromise of the WordPress website and the underlying server.
