CVE-2026-36723 Details
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).
A vulnerability allowing unrestricted file renaming has been identified in BookCars version 8.3 and earlier, specifically within the '/api/create-user' endpoint. This vulnerability allows authenticated attackers to exploit directory traversal sequences, moving arbitrary files from temporary storage to any location on the server filesystem. The issue arises because user-supplied data is not properly validated or sanitized before being used in file operations. As a result, attackers could gain unauthorized access to sensitive files, overwrite critical application files, and potentially execute remote code by replacing dynamically imported JavaScript modules.
