high Tenable Self-Hosted Container Security Plugin ID 441406

Description

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

 - Flight is an extensible micro-framework for PHP. Prior to 3.18.1, Flight::jsonp() concatenates the ?jsonp=
 query parameter directly into an application/javascript response body without validating that the value is
 a legal JavaScript identifier. An attacker can inject arbitrary JavaScript that executes in the response
 origin, enabling reflected cross-site scripting. This vulnerability is fixed in 3.18.1. (CVE-2026-42548)

Solution

Update the flightphp/core library and its related packages to version 3.18.1 or later.
