FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.19.0, FileRise validates the complete folderName string but does not reject dot-dot path segments before FolderModel::createFolder() constructs and creates the destination. An authenticated low-privileged user with a valid CSRF token and create or owner permission on the parent can submit traversal segments to POST /api/folder/createFolder.php and create directories outside UPLOAD_DIR wherever the web-server account can write. This issue is fixed in version 3.19.0.

CVSS

Base score: 5.4
Version: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.29 %
Percentile among all scored CVEs: 20
Score date: 10/20/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
