The fix adds CSRF token requirements and restricts methods to POST for the `set_widget` and `remove_widget` routes in `tawk_to.routing.yml`. It also updates `TawkToWidgetController` to generate URLs with CSRF tokens and modifies `tawk-to-iframe.html.twig` to use these secure URLs when making requests.

Also in this release The release replaces jQuery with vanilla JavaScript in the iframe template, improves autoescaping in templates, and adds entity decoding for user details in `TawkToEmbedRender`.

Tell me who you are, what your organisation does, and what you need. That might be a Drupal site that needs looking after, an upgrade to get done before December, or an agency that needs Drupal cover.

If I can help, I'll say so and suggest a call. If I can't, I'll tell you straight away rather than waste your time.

For context: I work mainly with UK charities, membership bodies and research organisations, and with the agencies that look after their websites. Not recruiters.

Or start smaller and connect with me on LinkedIn. That's where I post what I find digging around in charity and grants data, and where the free tools turn up first.
