What is CVE-2026-61502?

The Rejetto HFS web server versions 3.0.0 to 3.2.0 are susceptible to a Cross-Site Request Forgery (CSRF) vulnerability due to improper handling of GET requests. This oversight allows attackers to perform unauthorized administrative actions, such as account creation and configuration modifications. By enticing a logged-in administrator to click a malicious link, an attacker can execute these actions, potentially leading to code execution. Furthermore, if the attack is initiated from the server itself, unauthorized access can occur without any administrative credentials.

Affected Version(s)

hfs 3.0.0
