- Also known as: GHSA-JP5J-9PX9-G47G

- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 3.14.0

## Affected

- error311 FileRise: fixed in 3.14.0

## Description

FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.14.0, FileRise authenticates requests to the file creation and share-link creation handlers but does not enforce the server-side CSRF token check used by adjacent state-changing operations. The POST endpoints /api/file/createFile.php and /api/file/createShareLink.php invoke FileController::createFile and FileController::createShareLink without rejecting a missing or invalid X-CSRF-Token header. A request issued with a logged-in user's session can create an empty file or create a share link with that user's permissions, although the default SameSite=Lax session cookie reduces ordinary cross-site POST reachability. This issue is fixed in version 3.14.0.
