CVE-2025-31603

Vulnerability

Overview The CF7 Spreadsheets plugin for WordPress suffers from a missing authorization vulnerability in versions up to and including 2.3.2. This flaw allows an attacker to exploit incorrectly configured access control security levels, specifically enabling unauthorized changes to plugin settings [1].

Exploitation

An attacker can exploit this vulnerability without requiring any authentication or user interaction. By sending crafted requests to the vulnerable endpoint, they can modify the plugin's configuration. This attack can be performed remotely over the network, making it accessible to any unauthenticated user [1].

Impact

Successful exploitation allows an attacker to alter the plugin's settings, potentially redirecting form submissions, changing spreadsheet integration parameters, or disabling security features. This could lead to data exfiltration or further compromise of the WordPress installation. The vulnerability is known to be used in mass-exploit campaigns targeting thousands of websites [1].

Mitigation

Users are strongly advised to update the CF7 Spreadsheets plugin to the latest available version immediately. If updating is not possible, consult with a hosting provider or web developer for alternative security measures [1].
