CVE-2025-14632: Filr – Secure document library <= 1.2.11 – Authenticated (Administrator+) Stored Cross-Site Scripting via HTML Upload (filr-protection)

Severity Medium (CVSS 4.4)
CWE 434
Vulnerable Version 1.2.11
Patched Version 1.2.12
Disclosed January 15, 2026

Analysis Overview

Atomic Edge analysis of CVE-2025-14632:
This vulnerability is an authenticated stored cross-site scripting (XSS) issue in the Filr WordPress plugin. The plugin’s file upload functionality lacks proper file type validation, allowing administrators to upload malicious HTML files containing JavaScript. When users access these uploaded files, the embedded scripts execute in their browser context. The vulnerability affects all plugin versions up to and including 1.2.11 and has a CVSS score of 4.4.

The root cause lies in the FILR_Uploader class within the filr-protection/inc/classes/class-filr-uploader.php file. The upload_file() method (lines 81-120) processes file uploads without sufficient validation of file extensions or MIME types. The method accepts files through the $_FILES superglobal and saves them directly to the server’s upload directory. The vulnerability exists because the plugin only checks for basic file existence and upload errors but does not validate whether the uploaded file is a legitimate document type versus a malicious HTML file containing JavaScript payloads.

Exploitation requires an authenticated attacker with Administrator-level privileges or higher who can create or edit posts with the ‘filr’ post type. The attacker uploads an HTML file containing JavaScript payloads through the plugin’s file upload interface. The attack vector targets the AJAX endpoint at /wp-admin/admin-ajax.php with the action parameter set to ‘filr_upload_file’. The payload consists of a multipart/form-data POST request containing the malicious HTML file. Once uploaded, the file receives a publicly accessible URL within the WordPress uploads directory, typically at /wp-content/uploads/filr/{year}/{month}/filename.html.

The patch in version 1.2.12 introduces proper file type validation. The FILR_Uploader class now includes a validate_file_type() method that checks both file extensions and MIME types against an allowed list. The validation restricts uploads to common document formats like PDF, DOC, DOCX, XLS, XLSX, PPT, PPTX, TXT, and image files while explicitly blocking HTML, HTM, and other web-executable formats. The fix also implements proper sanitization of file names and adds security headers when serving files to prevent content sniffing attacks.

Successful exploitation allows attackers to execute arbitrary JavaScript in the context of any user who views the uploaded HTML file. This enables session hijacking, account takeover, administrative actions performed on behalf of victims, and data exfiltration. Since the vulnerability requires administrator privileges, the primary risk involves privilege escalation where compromised administrator accounts can maintain persistent backdoors through stored XSS payloads that affect all site visitors with appropriate file permissions.
