Due to the complexity of the required conditions, an attacker with low privileges could send specially crafted requests to bypass authorization checks and reach protected resources beyond their assigned scope. Successful exploitation could allow the attacker to read sensitive data and perform limited modifications on protected resources, resulting in a high impact on confidentiality and a low impact on integrity. There is no impact on availability.","published":"2026-08-11T01:17:24.000Z","lastModified":"2026-10-24T16:10:00.000Z","status":"Analyzed","sourceIdentifier":"cna@sap.com","cvss":{"version":"3.1","score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:N"},"cwe":["CWE-22"],"affected":["sap/approuter"],"epss":{"score":0.00439,"percentile":0.38,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.44%).
