What is CVE-2017-15235?

A remote attacker can exploit a vulnerability in the File Manager (gollem) module of Horde Groupware to bypass authentication when attempting file downloads.

This security oversight poses significant risks to data integrity and confidentiality, emphasizing the need for immediate patching and robust security measures.
