TIMELINE Sep 24 Reserved by VulnCheck Sep 24 Published (CNA: VulnCheck) Sep 28 EXPLOIT PUBLISHED — CVE-2026-97359 (rejetto hfs2). Public exploit reference added.
HFS2 version 2.4.0 and earlier contains a template injection vulnerability in the multipart upload handler that allows unauthenticated attackers to achieve remote code execution by embedding malicious template syntax in a filename. Attackers can craft a filename containing a closing template quoting sequence followed by an exec macro, which bypasses the authorization check in the dispatcher to execute arbitrary commands on the underlying host system.
