CVE-2023-37474 WRITEUP HIGH WRITEUP
copyparty < 1.8.2 - Path Traversal via .cpr Subfolder
Copyparty is a portable file server. Versions prior to 1.8.2 are subject to a path traversal vulnerability detected in the `.cpr` subfolder. The Path Traversal attack technique allows an attacker access to files, directories, and commands that reside outside the web document root directory. This issue has been addressed in commit `043e3c7d` which has been included in release 1.8.2. Users are advised to upgrade. There are no known workarounds for this vulnerability.

CVE-2023-38501 WRITEUP MEDIUM WRITEUP
copyparty < 1.8.7 - Reflected Cross-Site Scripting via URL Parameters
copyparty is file server software. Prior to version 1.8.7, the application contains a reflected cross-site scripting via URL-parameter `?k304=...` and `?setck=...`. The worst-case outcome of this is being able to move or delete existing files on the server, or upload new files, using the account of the person who clicks the malicious link. It is recommended to change the passwords of one's copyparty accounts, unless one have inspected one's logs and found no trace of attacks. Version 1.8.7 contains a patch for the issue.
CVSS 6.3
CVE-2025-54589 WRITEUP MEDIUM WRITEUP
copyparty < 1.18.7 - Reflected Cross-Site Scripting via Recent Uploads Filter Parameter
Copyparty is a portable file server. In versions 1.18.6 and below, when accessing the recent uploads page at `/?ru`, users can filter the results using an input field at the top. This field appends a filter parameter to the URL, which reflects its value directly into a `<script>` block without proper escaping, allowing for reflected Cross-Site Scripting (XSS) and can be exploited against both authenticated and unauthenticated users. This is fixed in version 1.18.7.
CVSS 6.3
CVE-2026-30974 WRITEUP MEDIUM WRITEUP
copyparty < 1.20.11 - Stored Cross-Site Scripting via SVG Upload
Copyparty is a portable file server. Prior to v1.20.11., the nohtml config option, intended to prevent execution of JavaScript in user-uploaded HTML files, did not apply to SVG images. A user with write-permission could upload an SVG containing embedded JavaScript, which would execute in the context of whichever user opens it. This has been fixed in v1.20.11.
CVSS 4.6
CVE-2026-27948 WRITEUP MEDIUM WRITEUP
Copyparty < 1.20.9 - Reflected Cross-Site Scripting via URL Parameter
Copyparty is a portable file server. In versions prior to 1.20.9, an XSS allows for reflected cross-site scripting via URL-parameter `?setck=...`. Version 1.20.9 fixes the issue.
CVSS 5.4
CVE-2025-27145 WRITEUP LOW WRITEUP
copyparty < 1.16.15 - DOM-based Cross-Site Scripting via Drag-and-Drop File Upload
copyparty, a portable file server, has a DOM-based cross-site scripting vulnerability in versions prior to 1.16.15. The vulnerability is considered low-risk. By handing someone a maliciously-named file, and then tricking them into dragging the file into copyparty's Web-UI, an attacker could execute arbitrary javascript with the same privileges as that user. For example, this could give unintended read-access to files owned by that user. The bug is triggered by the drag-drop action itself; it is not necessary to actually initiate the upload. The file must be empty (zero bytes). Note that, as a general-purpose webserver, it is intentionally possible to upload HTML-files with arbitrary javascript in `<script>` tags, which will execute when the file is opened. The difference is that this vulnerability would trigger execution of javascript during the act of uploading, and not when the uploaded file was opened. Version 1.16.15 contains a fix.
CVSS 3.6
CVE-2025-54423 WRITEUP MEDIUM WRITEUP
copyparty <= 1.18.4 - Unauthenticated Stored Cross-Site Scripting via Multimedia Tag Handling
copyparty is a portable file server. In versions up to and including versions 1.18.4, an unauthenticated attacker is able to execute arbitrary JavaScript code in a victim's browser due to improper sanitization of multimedia tags in music files, including m3u files. This is fixed in version 1.18.5.
CVSS 5.4
CVE-2025-54796 WRITEUP HIGH WRITEUP
copyparty < 1.18.9 - Denial of Service via Filter Parameter Regular Expression
Copyparty is a portable file server. Versions prior to 1.18.9, the filter parameter for the "Recent Uploads" page allows arbitrary RegExes. If this feature is enabled (which is the default), an attacker can craft a filter which deadlocks the server. This is fixed in version 1.18.9.
CVSS 7.5
CVE-2025-58753 WRITEUP HIGH WRITEUP
Copyparty <1.19.8 - Info Disclosure
Copyparty is a portable file server. In versions prior to 1.19.8, there was a missing permission-check in the shares feature (the `shr` global-option). When a share was created for just one file inside a folder, it was possible to access the other files inside that folder by guessing the filenames. It was not possible to descend into subdirectories in this manner; only the sibling files were accessible. This issue did not affect filekeys or dirkeys. Version 1.19.8 fixes the issue.
