The vulnerability CVE-2025-50040 affects the moshensky CF7 Spreadsheets plugin (versions up to 2.3.2) and involves improper neutralization of input during web page generation, resulting in stored cross-site scripting (XSS). This allows an attacker with limited privileges and requiring user interaction to inject malicious scripts that can impact confidentiality, integrity, and availability to a limited extent. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with a scope change and partial impact on confidentiality, integrity, and availability.

Successful exploitation can lead to execution of arbitrary scripts in the context of the affected web application, potentially allowing attackers to steal user data, perform actions on behalf of users, or disrupt application availability. The impact is rated medium due to the requirement for privileges and user interaction and partial impact on confidentiality, integrity, and availability. There are no reports of active exploitation in the wild.
