SCA: security update for parse-server (GHSA-hcj7-6gxh-24ww)

high Tenable Self-Hosted Container Security Plugin ID 438608

Description

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

 - Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js.
 Prior to 9.5.2-alpha.4 and 8.6.17, a stored cross-site scripting (XSS) vulnerability allows any
 authenticated user to upload an SVG file containing JavaScript. The file is served inline with Content-
 Type: image/svg+xml and without protective headers, causing the browser to execute embedded scripts in the
 Parse Server origin. This can be exploited to steal session tokens from localStorage and achieve account
 takeover. The default fileExtensions option blocks HTML file extensions but does not block SVG, which is a
 well-known XSS vector. All Parse Server deployments where file upload is enabled for authenticated users
 (the default) are affected. This vulnerability is fixed in 9.5.2-alpha.4 and 8.6.17. (CVE-2026-30948)

Solution

Update the parse-server library and its related packages to version 8.6.17 or later.
