CVE-2025-8593: 
WordPress vulnerability analysis and mitigation

The GSheetConnector For Gravity Forms plugin for WordPress is vulnerable to authorization bypass in versions less than, or equal to, 1.3.27. This vulnerability was discovered and disclosed on October 10, 2025, and is tracked as CVE-2025-8593. The vulnerability affects the WordPress plugin's 'install_plugin' function and has been assigned a CVSS v3.1 score of 8.8 (High) (Wordfence).

The vulnerability stems from a missing capability check on the 'install_plugin' function. This security flaw allows authenticated attackers with subscriber-level access or higher to install plugins on the target site. The vulnerability has been assigned CWE-862 (Missing Authorization) classification. The CVSS v3.1 vector string is CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating network accessibility, low attack complexity, and high impact across confidentiality, integrity, and availability (NVD).

The vulnerability allows authenticated attackers to install arbitrary plugins on the affected WordPress site. Under certain conditions, this could lead to arbitrary code execution on the server. The high CVSS score reflects the severe potential impact, as successful exploitation could compromise the confidentiality, integrity, and availability of the affected system (Rapid7).

Users should immediately update the GSheetConnector For Gravity Forms plugin to a version newer than 1.3.27. The vulnerability has been patched in subsequent releases. If immediate updating is not possible, consider temporarily deactivating the plugin until an update can be applied (NVD).
