Does it apply to youSites are affected if the discussion area does not use the default selection tool or if content is created through a web services data feed.

For developers: what the fix changed

The fix introduces a new validation constraint, `ForumAccessCreate`, and attaches it to the `taxonomy_forums` field via `forum_access_entity_bundle_field_info_alter()` in `forum_access.module`. The constraint validator in `ForumCreateAccessConstraintValidator.php` enforces the 'create' grant on the forum, ensuring access checks apply to all input methods including autocomplete widgets and APIs.

Also in this release Added a post-update hook to rebuild caches and updated a test group annotation.

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 membership bodies, charities 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.
