SCA: security update for symfony/ux-autocomplete (GHSA-mwqm-4fw3-cjvr)

medium Tenable Cloud Security Plugin ID 443629

Description

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

- Symfony UX is a JavaScript ecosystem for Symfony. From 2.2.0 until 2.36.0 and 3.1.0, the Stimulus
controller in symfony/ux-autocomplete renders AJAX response items in _createAutocompleteWithRemoteData()
by interpolating the text field into HTML template literals (<div>${item[labelField]}</div>) rather than
text, allowing attacker-controlled markup from user-supplied dropdown values to execute in the browser of
any user who opens an autocomplete widget backed by the same data. This issue is fixed in versions 2.36.0
and 3.1.0. (CVE-2026-49216)

Solution

Update the symfony/ux-autocomplete library and its related packages to version 2.36.0 or later.
