Technical details
The vulnerability is a classic path traversal flaw (CWE-22) in hekto versions before 0.2.3 that allows remote attackers to bypass directory restrictions and access arbitrary files on the system. The attack requires no authentication and is network-accessible, making it trivial to exploit. By crafting malicious file path requests (e.g., using ../ sequences), an attacker can read the contents of any file readable by the application process. The vulnerability was fixed in version 0.2.3 and later.
