For developers: what the fix changed

The fix introduces a new `_mm_content_escape_name` function in `mm_content.inc` that sanitises page names using `strip_tags` and `Xss::filter`, and applies it to the return values of `mm_content_expand_name` and `mm_content_get_name`.

Also in this release Added a functional JavaScript test to ensure JavaScript in page names is not evaluated.

Get in touch

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.
