The vulnerability identified as CVE-2025-58213 affects the ameliabooking Booking System Trafft (versions <= 1.0.14). It is a stored cross-site scripting (XSS) flaw caused by improper input neutralization during web page generation. This allows an attacker with low privileges to inject malicious scripts that can be executed in the context of other users' browsers, potentially leading to limited confidentiality, integrity, and availability impacts. The CVSS 3.1 vector indicates network attack vector, low attack complexity, low privileges required, user interaction required, and scope change, with low impact on confidentiality and integrity and low impact on availability.

An attacker with low privileges can inject malicious scripts that are stored and later executed in the browsers of other users interacting with the affected system. This can lead to limited compromise of confidentiality and integrity of user data and potentially impact availability. The attack requires user interaction and low privileges, which lowers the barrier to exploitation but limits the overall impact to medium severity.
