CVE-2026-33653 is a stored cross-site scripting (XSS) vulnerability in the farisc0de Uploady file uploader script versions prior to 3. 1. 2. The vulnerability arises from improper sanitization of filenames during the file upload process, allowing an attacker to upload files with malicious JavaScript code embedded in the filename. This code executes in the browser of any user who views the affected file list or details page. The issue is fixed in version 3. 1. 2.
AI Analysis
Technical Summary
The vulnerability in farisc0de Uploady (versions before 3.1.2) is a stored XSS caused by insufficient neutralization of input in filenames during file uploads. Malicious JavaScript embedded in a filename is stored and later rendered without proper escaping, leading to script execution in users' browsers when they view the file list or details. This can lead to limited confidentiality and integrity impacts as indicated by the CVSS vector. The vulnerability has a CVSS 3.1 base score of 4.6 (medium severity).
Potential Impact
Successful exploitation allows an attacker to execute arbitrary JavaScript in the context of users viewing the file list or details page, potentially leading to information disclosure or manipulation of client-side data. The CVSS score reflects limited confidentiality and integrity impact with no availability impact. There are no known exploits in the wild at this time.
Mitigation Recommendations
Upgrade farisc0de Uploady to version 3.1.2 or later, where this vulnerability is fixed. Since this is a software vulnerability and not a cloud service, patching the affected software version is required. No additional vendor advisory is provided, so patch status is based on the version information in the description.
