{"id":"CVE-2026-61726","state":"PUBLISHED","title":"Tandoor Recipes: Private recipe authorization bypass via /api/step/ - read and modify another Space member's private recipe content","description":"Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.6.12, StepViewSet and IngredientViewSet filter only by active Space and use role-level CustomIsUser checks instead of the private-recipe owner or sharing predicate when an authenticated user with read and write API scope in the victim's Space supplies a private recipe or step identifier to the Step API. Request processing uses StepViewSet, IngredientViewSet, api/step/, api/step/{step_id}/, CustomIsUser, CustomRecipePermission. The attack works because the sub-resource querysets return and update private-recipe steps for non-owners because Space membership is accepted without recipe-level authorization. This can read and silently modify another same-Space member's private recipe instructions, while cross-Space access remains out of scope. This issue is fixed in version 2.6.12.","publishedAt":"2026-10-16T19:19:57.552Z","updatedAt":"2026-10-28T18:00:30.729Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["TandoorRecipes recipes"],"affected":[{"vendor":"TandoorRecipes","product":"recipes","versions":[{"version":"< 2.6.12","status":"affected"}]}],"references":["https://github.com/TandoorRecipes/recipes/security/advisories/GHSA-wjf3-fq5w-7j7w","https://github.com/TandoorRecipes/recipes/commit/3c5678f663e62e6ddf3d7df0b2bcc89ce2f52def","https://github.com/TandoorRecipes/recipes/releases/tag/2.6.12"],"weaknesses":["CWE-284","CWE-639","CWE-863"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/61xxx/CVE-2026-61726.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-61726","state":"PUBLISHED","datePublished":"2026-10-16T19:19:57.552Z","dateUpdated":"2026-10-28T18:00:30.729Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-10T18:59:00.046Z"},"containers":{"cna":{"title":"Tandoor Recipes: Private recipe authorization bypass via /api/step/ - read and modify another Space member's private recipe content","descriptions":[{"lang":"en","value":"Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists.
