SCA: security update for phlex (GHSA-9p57-h987-4vgx)

high Tenable Self-Hosted Container Security Plugin ID 413382

Description

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

- Phlex is a framework for building object-oriented views in Ruby. In affected versions there is a potential
cross-site scripting (XSS) vulnerability that can be exploited via maliciously crafted user data. Since
the last two vulnerabilities https://github.com/phlex-ruby/phlex/security/advisories/GHSA-242p-4v39-2v8g
and https://github.com/phlex-ruby/phlex/security/advisories/GHSA-g7xq-xv8c-h98c, we have invested in
extensive browser tests. It was these new tests that helped us uncover these issues. As of now the project
exercises every possible attack vector the developers can think of — including enumerating every ASCII
character, and we run these tests in Chrome, Firefox and Safari. Additionally, we test against a list of
6613 known XSS payloads (see: payloadbox/xss-payload-list). The reason these issues were not detected
before is the escapes were working as designed. However, their design didn't take into account just how
recklessly permissive browsers are when it comes to executing unsafe JavaScript via HTML attributes. If
you render an `<a>` tag with an `href` attribute set to a user-provided link, that link could potentially
execute JavaScript when clicked by another user. If you splat user-provided attributes when rendering any
HTML or SVG tag, malicious event attributes could be included in the output, executing JavaScript when the
events are triggered by another user. Patches are available on RubyGems for all minor versions released in
the last year. Users are advised to upgrade. Users unable to upgrade should configure a Content Security
Policy that does not allow `unsafe-inline` which would effectively prevent this vulnerability from being
exploited. Users who upgrade are also advised to configure a Content Security Policy header that does not
allow `unsafe-inline`. (CVE-2024-32970)
