This vulnerability (CVE-2025-31573) affects Pepro Dev. Group's PeproDev CF7 Database plugin, specifically versions up to 2.0.0. It is a stored cross-site scripting (XSS) issue caused by improper input neutralization during web page generation. The CVSS 3.1 base score is 7.1, indicating high severity, with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability. The vulnerability allows attackers to inject malicious scripts that persist and execute in users' browsers when viewing affected pages.

Successful exploitation can lead to partial compromise of confidentiality, integrity, and availability of affected systems or user data due to stored XSS. Attackers may execute arbitrary scripts in the context of users' browsers, potentially leading to session hijacking, data theft, or other malicious actions. However, no known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider disabling or limiting use of the affected plugin version and apply standard XSS mitigations such as input validation and output encoding where possible. Monitor vendor communications for updates on patches or official fixes.
