CVE-2026-50878 Details
Description
An issue in the attachment handling component of Feuerhamster MailForm v1.1.0 allows attackers to cause a Denial of Service (DoS) via a crafted request.
A denial-of-service vulnerability has been identified in Feuerhamster MailForm version 1.1.0. The issue arises in the attachment handling component, where the application fails to properly clean up temporary files after processing form submissions. This oversight allows attackers to accumulate files in the server's temporary directory by repeatedly sending multipart requests with file attachments. The problem can be exacerbated by using delivery settings that cause email sending to fail, leaving the uploaded files behind.
