Put simply

Think of it as a mailroom that accepts any package without inspecting it โ€” a dangerous delivery service that allows anyone to send malicious files disguised as legitimate mail. This vulnerability allows attackers to upload files of any type without proper validation, enabling the execution of malicious code on the server.

This means your entire website and user data are on the line, which is absolutely devastating. To mitigate this risk, immediately update the AcyMailing component to the latest version. Ensure strict file type validation and consider implementing a file upload whitelist to only allow known safe types. Regularly review and audit file upload functionalities to strengthen security.
