{"id":"CVE-2026-61726","summary":"Tandoor Recipes: Private recipe authorization bypass via /api/step/ - read and modify another Space member's private recipe content","details":"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.","aliases":["GHSA-wjf3-fq5w-7j7w"],"modified":"2026-10-21T02:58:52.505124629Z","published":"2026-10-16T19:19:57.552Z","database_specific":{"cwe_ids":["CWE-284","CWE-639","CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61726.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61726.json"},{"type":"FIX","url":"https://github.com/TandoorRecipes/recipes/commit/3c5678f663e62e6ddf3d7df0b2bcc89ce2f52def"},{"type":"WEB","url":"https://github.com/TandoorRecipes/recipes/releases/tag/2.6.12"},{"type":"ADVISORY","url":"https://github.com/TandoorRecipes/recipes/security/advisories/GHSA-wjf3-fq5w-7j7w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61726"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/tandoorrecipes/recipes","events":[{"introduced":"0"},{"fixed":"bf3a5a6b378669783bc6558b53be206540ea83d9"},{"fixed":"3c5678f663e62e6ddf3d7df0b2bcc89ce2f52def"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StringRangeExpression","range":[{"introduced":"0"},{"fixed":"2.6.12"}]},{"source":"REFERENCES_COMMIT","range":[{"fixed":"3c5678f663e62e6ddf3d7df0b2bcc89ce2f52def"}]},{"original_tag":"2.6.12","range":[{"fixed":"bf3a5a6b378669783bc6558b53be206540ea83d9"}],"source":"REFERENCES_TAG"}]}}],"versions":["2.6.11","2.6.10","2.6.9","2.6.8","2.6.7","2.6.6","2.6.5","2.6.4","2.6.3","2.6.2","2.6.1","2.6.0","2.5.3","2.5.2","2.5.1","2.5.0","2.4.2","2.4.1","2.4.0","2.3.6","2.3.5","2.3.4","2.3.3","2.3.2","2.3.0","2.2.7","2.0.0-alpha-6","2.0.0-alpha-5","2.0.0-alpha-4","2.0.0-alpha-3","2.0.0-alpha-2","2.0.0-alpha-1","1.5.11","1.2.5","1.2.4","1.1.4","1.1.3","1.0.3","0.17.3","0.17.2","0.17.1","0.16.0","0.15.2","0.15.1","0.15.0","0.13.0","0.12.1","0.12.0","0.11.2","0.11.1","0.11.0","0.10.1","0.10.0","0.9.2","0.9.1","0.9.0","0.7.1","0.7.0","0.6.5","0.6.4","0.6.3","0.6.2","0.6.1","0.6.0","0.5.1","0.5.0","0.4.0","0.3.2","0.3.1","0.3.0","0.2.2","0.2.1","0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-61726.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"}]}
