Summary

File Browser is vulnerable to Stored Cross-site Scripting via crafted EPUB file

Details

Summary

The EPUB preview function in File Browser is vulnerable to Stored Cross-site Scripting (XSS). JavaScript embedded in a crafted EPUB file executes in the victim's browser when they preview the file.

Details

frontend/src/views/files/Preview.vue passes allowScriptedContent: true to the vue-reader (epub.js) component:

// frontend/src/views/files/Preview.vue (Line 87)
:epubOptions="{
  allowPopups: true,
  allowScriptedContent: true,
}"

epub.js renders EPUB content inside a sandboxed with srcdoc. However, the sandbox includes both allow-scripts and allow-same-origin, which renders the sandbox ineffective — the script can access the parent frame's DOM and storage.

The epub.js developers explicitly warn against enabling scripted content.

PoC

I've crafted the PoC python script that could be ran on test environment using docker compose:

services:

  filebrowser:
    image: filebrowser/filebrowser:v2.62.1
    user: 0:0
    ports:
      - "80:80"

And running this PoC python script:

import argparse
import io
import sys
import zipfile
import requests

[*] ATTACK BEGINS...
====================
  [1] Authenticating to http://localhost
      Logged in as: admin

  [2] Building malicious EPUB
      EPUB size: 1927 bytes

  [3] Uploading to /poc_xss_test.epub
      Upload OK (200)

  [4] Done
      Preview URL: http://localhost/files/poc_xss_test.epub
====================


Open the URL above in a browser. You should see:
  - Red text:    "XSS OK" + stolen JWT token
  - Orange text: victim's public IP (via ifconfig.me)

NOTE: alert() is blocked by iframe sandbox (no allow-modals).
The attack is silent — JWT theft and network exfiltration work.

Impact

JWT token theft — full session hijacking
Privilege escalation — a low-privilege user with upload (Create) permission can steal an admin's token

7.6 (High)

CVE-2026-34529 (GCVE-0-2026-34529)

Vulnerability from cvelistv5 – Published: 2026-04-01 20:39 – Updated: 2026-04-02 15:41

Title

File Browser is vulnerable to Stored Cross-site Scripting via crafted EPUB file

Summary

File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to version 2.62.2, the EPUB preview function in File Browser is vulnerable to Stored Cross-Site Scripting (XSS). JavaScript embedded in a crafted EPUB file executes in the victim's browser when they preview the file. This issue has been patched in version 2.62.2.

Severity ?
