CVE-2026-4020

69
FAUCET Score

The Gravity SMTP plugin for WordPress, in versions up to and including 2.1.4, is vulnerable to sensitive information exposure. This high-severity flaw (CVSS 7.5) allows unauthenticated attackers to access a REST API endpoint that, when a specific query parameter is used, returns a detailed system report. This includes critical system configuration data such as PHP and web server versions, database details, WordPress configuration, active plugins, and potentially API keys. There is currently no evidence of active exploitation or public exploit code, though the vulnerability has received some community discussion across various platforms.
