SCA: security update for code16/sharp (GHSA-fr76-5637-w3g9)

high Tenable Self-Hosted Container Security Plugin ID 439229

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Sharp is a content management framework built for Laravel as a package. Versions prior to 9.20.0 contain a
 vulnerability in the file upload endpoint that allows authenticated users to bypass all file type
 restrictions. The upload endpoint within the `ApiFormUploadController` accepts a client-controlled
 `validation_rule` parameter. This parameter is directly passed into the Laravel validator without
 sufficient server-side enforcement. By intercepting the request and sending `validation_rule[]=file`, an
 attacker can completely bypass all MIME type and file extension restrictions. This issue has been
 addressed in version 9.20.0 by removing the client-controlled validation rules and strictly defining
 upload rules server-side. As a workaround, ensure that the storage disk used for Sharp uploads is strictly
 private. Under default configurations, an attacker cannot directly execute uploaded PHP files unless a
 public disk configuration is explicitly used. (CVE-2026-33687)

Solution

Update the code16/sharp library and its related packages to version 9.20.0 or later.
