This vulnerability in Mollie Forms (<= 2.7.12) involves improper input neutralization leading to stored cross-site scripting. An attacker with low privileges can inject malicious scripts that are stored and later executed in the context of other users. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with impacts on confidentiality, integrity, and availability at a low level. No patch or vendor advisory details are provided, and the product is not a cloud service.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of users viewing the affected web pages, potentially leading to data disclosure, modification, or disruption of service. The impact is rated medium based on the CVSS score of 6.5. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider restricting privileges to trusted users and minimizing exposure to untrusted input. Monitor official channels for updates from the vendor Nick van Wobbie regarding patches or mitigations.
