The vulnerability CVE-2025-50053 affects the nebelhorn Blappsta Mobile App Plugin, specifically versions up to 0.8.8.8. It is a reflected Cross-site Scripting (XSS) issue caused by improper input neutralization during web page generation. This allows an attacker to inject malicious scripts that are reflected back to users, potentially impacting confidentiality, integrity, and availability of the affected application. The CVSS v3.1 score is 7.1 with vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L, indicating network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and partial impacts to confidentiality, integrity, and availability. No vendor advisory or patch information is available, and no known exploits have been reported.

Successful exploitation of this reflected XSS vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected application, potentially leading to partial loss of confidentiality, integrity, and availability. This could result in unauthorized actions performed on behalf of users or exposure of sensitive information. However, no known exploits are currently reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution with untrusted input and consider implementing input validation or output encoding as temporary mitigations if feasible.
