Description

Casdoor: Arbitrary file write possible through Local File System storage provider

An arbitrary file write vulnerability exists in Casdoor's Local File System storage provider. Due to insufficient path sanitization, an authenticated attacker with administrative privileges can perform a Path Traversal attack to create or overwrite arbitrary files anywhere on the host filesystem, bypassing the application's intended storage sandbox.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality low, integrity low, availability low.

Weakness class

CVE-2026-6815 is classified as CWE-22: Path Traversal. A file path built from user input is not confined to the intended directory, letting an attacker reach files elsewhere on the filesystem.
