## Description

Directory Traversal vulnerability in Fohrloop Dash-Uploader v.0.1.0 through v.0.7.0a2 allows a remote attacker to execute arbitrary code via the dash_uploader/httprequesthandler.py, aseHttpRequestHandler.get_temp_root(), BaseHttpRequestHandler._post() components

## CrowdSec analysis

[CVE-2026-38360](https://euvd.enisa.europa.eu/vulnerability/CVE-2026-38360) is a critical directory traversal vulnerability in Fohrloop Dash-Uploader versions 0.1.0 through 0.7.0a2, which allows remote attackers to execute arbitrary code by exploiting flaws in the HTTP request handling components. This vulnerability could be leveraged to gain unauthorized access to sensitive files or execute malicious payloads on the affected system, posing a severe risk to data integrity and system security.

CrowdSec has been tracking this vulnerability and its exploits since 3rd of June 2026.

CrowdSec network observations suggest that most exploitation of CVE-2026-38360 involves focused reconnaissance to identify viable targets. Attackers typically tailor their campaigns based on system exposure and configuration. It is unlikely that a given attack is accidental.
CrowdSec data also reveals a clear uptick in attacks involving CVE-2026-38360 over the past week. Activity is above the usual baseline, suggesting growing attention from attackers. This may reflect rising awareness, recent exploit releases, or expanded targeting efforts.

Attackers exploit this vulnerability by sending crafted POST requests to `/API/dash-uploader` or `/API/resumable` with path traversal sequences in the `upload_id` parameter, allowing arbitrary files to be written to unintended locations such as `/assets/`.
