Tell your developerUpdate Islandora to 2.17.5.

For developers: what the fix changed

The fix adds a `validateContentLocation` method in `src/MediaSource/MediaSourceService.php` to sanitize the `Content-Location` header, preventing path traversal and ensuring it is a valid stream wrapper URI. It also introduces `determinePersistedMimeType` to securely guess the MIME type of uploaded files instead of trusting user input.

Also in this release Added automated tests to verify the new path traversal and MIME-type spoofing protections.

Not sure what your site is running?

Send me your Drupal site's address.

I'll tell you what I can see from outside, what the Drupal 10 end of life on 9 December means for it, and what it would cost to have me keep it patched. There's no charge for that and no obligation. peter@peterbrady.co.uk

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.
