SCA: security update for wintercms/winter (GHSA-wjw2-4j7j-6gc3)

medium Tenable Self-Hosted Container Security Plugin ID 419979

Description

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

 - Winter is a free, open-source content management system (CMS) based on the Laravel PHP framework. Users
 with the `backend.manage_branding` permission can upload SVGs as the application logo. Prior to version
 1.2.3, SVG uploads were not sanitized, which could have allowed a stored cross-site scripting (XSS)
 attack. To exploit the vulnerability, an attacker would already need to have developer or super user level
 permissions in Winter CMS. This means they would already have extensive access and control within the
 system. Additionally, to execute the XSS, the attacker would need to convince the victim to directly visit
 the URL of the maliciously uploaded SVG, and the application would have to be using local storage where
 uploaded files are served under the same domain as the application itself instead of a CDN. This is
 because all SVGs in Winter CMS are rendered through an `img` tag, which prevents any payloads from being
 executed directly. These two factors significantly limit the potential harm of this vulnerability. This
 issue has been patched in v1.2.3 through the inclusion of full support for SVG uploads and automatic
 sanitization of uploaded SVG files. As a workaround, one may apply the patches manually. (CVE-2023-37269)
