{"schemaVersion":3,"id":"CVE-2026-58239","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"SAP Approuter does not sufficiently validate tenant context in inbound requests. An unauthenticated attacker could send specially crafted requests to spoof the tenant context under conditions not fully within their control. Successful exploitation could allow limited access to another tenant's information, resulting in a low impact on confidentiality. There is no impact on integrity and availability.","dates":{"published":"2026-08-11T00:15:40.747Z","modified":"2026-08-11T14:31:07.219Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":3.7,"severity":"low","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":3.7,"severity":"low","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":3.7,"severity":"low","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00346,"percentile":0.26864,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0.12599999999999997,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.0022},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.0022,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.0022,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.0022,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.0022,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.0022,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.0022,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.0022,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.0022,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.0022,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.0022,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00346,"percentile":0.26864}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.0022,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.0022,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.0022,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00346,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","sc
