For developers: what the fix changed

This release carries 2 security fixes. The summary below is for SA-CONTRIB-2026-052, the most serious of them.

The fix replaces the base64-encoded feedback ID with an HMAC-signed token in `AdminFeedbackController::insertFeedback()` and verifies this signature in `AdminFeedbackController::updateFeedback()` to prevent users from modifying arbitrary feedback records. It also updates `AdminFeedbackAjaxForm` to handle the validation result and ensures that a comment can only be set once per feedback record.

Also in this release Added flood control for vote submissions, batch processing for CSV exports, a feature to delete all feedback for a specific node, and made JavaScript markup themeable.

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.
