Moderately critical · 1,722 sites report using it · 2 security fixes · Week of 21 October 2026

2 security fixes in one update. Frontend Editing fixed 2 separate security bugs at once: 1 cross site request forgery (csrf), 1 access bypass. One update covers all of them. The most serious, SA-CONTRIB-2026-240, is explained here and the full list is at the end of the card.

The module does not sufficiently protect the pages used to delete and reorder paragraphs against forged requests. Anyone with no login could trick an editor into visiting a crafted link which deletes or reorders paragraphs on a piece of content using the editor's access rights. They could not view any restricted information.

Who could do thisAnyone visiting the site. No login needed.
Does it apply to youThe victim must be logged in with the access right to edit the content and to delete or move paragraphs.
Has it been used in attacksNo sign of it.

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 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.
