CVE-2025-7640 is a high-severity vulnerability in the den-media hiWeb Export Posts WordPress plugin (versions up to 0.9.0.0). It arises from improper nonce validation in the tool-dashboard-history.php file, enabling Cross-Site Request Forgery attacks. An attacker can exploit this by crafting a request that causes an authenticated site administrator to delete arbitrary files on the server. This improper limitation of pathname (CWE-22) can escalate to remote code execution if critical files like wp-config.php are deleted. The vulnerability requires user interaction (UI:R) but no privileges (PR:N) and is exploitable remotely (AV:N).

Successful exploitation allows an attacker to delete arbitrary files on the server by tricking a site administrator into performing a forged request. This can result in denial of service or remote code execution if key files such as wp-config.php are deleted. The vulnerability does not disclose data directly but impacts integrity and availability with high severity.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, administrators should avoid using the vulnerable versions of the hiWeb Export Posts plugin or restrict access to the affected functionality. Monitoring for suspicious administrator actions and applying strict access controls may reduce risk. Do not rely on generic mitigations unrelated to nonce validation or CSRF protection.
