SCA: security update for flightphp/core (GHSA-vxrr-w42w-w76g)

high Tenable Self-Hosted Container Security Plugin ID 441311

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, Request::getMethod() unconditionally
 honors the X-HTTP-Method-Override header and the $_REQUEST['_method'] parameter on any HTTP verb
 (including safe verbs such as GET), with no opt-in and no whitelist of permitted target methods. A GET
 request can silently become a DELETE or PUT, enabling CSRF escalation against destructive endpoints,
 bypass of middleware gated on unsafe verbs, and cache poisoning between CDN and origin. This vulnerability
 is fixed in 3.18.1. (CVE-2026-42551)

Solution

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