CVE-2026-35489 is a sibling vulnerability in the same Tandoorrecipes recipes advisory bundle as CVE-2026-35045. The same patched build closes every CVE in the bundle, so the remediation procedure for CVE-2026-35489 matches the primary write-up.

What is different about CVE-2026-35489?

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.6.4, the POST /api/food/{id}/shopping/ endpoint reads amount and unit directly from request.data and passes them without validation to ShoppingListEntry.objects.create(). Invalid amount values (non-numeric strings) cause an unhandled exception and HTTP 500.

Impact is consistent with the bundle: compromise of the affected component as described in the vendor advisory. The patched build closes every code path in the advisory in one update.

How to fix CVE-2026-35489

Apply the patched build per the primary write-up: How to Fix CVE-2026-35045.

For a quick check, confirm the running version of recipes:


# Confirm the installed version via your package manager
dpkg -l | grep -i recipes   # Debian/Ubuntu
rpm -qa | grep -i recipes   # RHEL/CentOS/Rocky

Frequently asked questions

Is CVE-2026-35489 being actively exploited?

Not at the time of writing. It is not listed in CISA's Known Exploited Vulnerabilities catalog. That status can change, so monitor the vendor advisory and the KEV catalog if the system is exposed.

How severe is CVE-2026-35489?

CVSS rates it 7.3 (High). Use that score to set your patch priority alongside the other items in your queue.

Do I have to take recipes offline to apply the patch?

It depends on the deployment. High-availability or clustered installs can usually patch one node at a time with no full outage. Standalone installs typically need a short restart. Always follow the vendor's documented upgrade steps.

What if my vulnerability scanner still flags CVE-2026-35489 after I patch?

Re-run the scan after a service restart, then confirm the scanner's plugin set is up to date. Some scanners detect by banner version only and lag the official fix metadata by a release.
