The vulnerability was identified on June 11, 2025, by Dave Jong from Patchstack and affects versions prior to 4.19.1. This security issue allows unauthenticated attackers to perform reflected XSS attacks (Wiz, Patchstack).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation) and has received a CVSS v3.1 score of 7.1 (HIGH).
