CVE-2026-35489: CWE-639: Authorization Bypass Through User-Controlled Key in TandoorRecipes recipes
CVE-2026-35489 is a high-severity vulnerability in Tandoor Recipes versions prior to 2. 6. 4. It involves the POST /api/food/{id}/shopping/ endpoint improperly handling user-supplied amount and unit data without validation. This can cause unhandled exceptions resulting in HTTP 500 errors and allows cross-space association of unit IDs, leading to potential leakage of foreign-key references across tenant boundaries. The issue is fixed in version 2. 6. 4.
AI Analysis
Technical Summary
Tandoor Recipes before version 2.6.4 contains an authorization bypass vulnerability (CWE-639) due to insufficient validation of user-controlled keys in the POST /api/food/{id}/shopping/ endpoint. Specifically, amount and unit fields are read directly from request data and passed to ShoppingListEntry.objects.create() without validation. Invalid amount values cause unhandled exceptions, and unit IDs from different tenant spaces can be associated cross-space, leaking foreign-key references. Other endpoints use a serializer that properly validates these fields. This vulnerability has a CVSS 3.1 score of 7.3 (high severity) and is fixed in version 2.6.4.
Potential Impact
Exploitation can lead to denial of service via unhandled exceptions (HTTP 500) and unauthorized cross-tenant data leakage by associating unit IDs from different spaces. This compromises data integrity and confidentiality across tenant boundaries within the application.
Mitigation Recommendations
Upgrade Tandoor Recipes to version 2.6.4 or later, where this vulnerability is fixed. There is no indication of alternative mitigations or temporary fixes. Patch status is not explicitly stated but the vendor fixed the issue in 2.6.4, so applying this official fix is recommended.
