Name of the Vulnerable Software and Affected Versions Tipask versions prior to 3.5.9

Description The issue allows a registered user to download arbitrary files on the Tipask server, such as .env, /etc/passwd, laravel.log, due to the lack of validation of path parameters entered by the user when downloading attachments. This can cause information leakage.

Recommendations For versions prior to 3.5.9, update to version 3.5.9 or later to resolve the issue. As a temporary workaround, consider restricting access to the attachment download feature to minimize the risk of exploitation.
