CVE-2026-36723

Description

An unrestricted file rename vulnerability in the /api/create-user component of bookcars v8.3 allows authenticated attackers to leverage directory traversal sequences to move arbitrary files from temporary storage to arbitrary locations on the server filesystem. This enables unauthorized access to sensitive files, the overwriting of critical application files, and remote code execution (RCE).
