The caveat here is that an attacker would need administrative privileges in order to create the payload. One might think this completely mitigates the privilege-escalation impact as there is only one high-privileged role. However, it was discovered that the endpoint responsible for creating the group lacks CSRF protection.","published":"2020-12-24T04:15:13.000Z","lastModified":"2026-06-17T03:14:07.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":4.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N"},"cwe":["CWE-79","CWE-352"],"affected":["bigprof/online invoicing system"],"epss":{"score":0.00334,"percentile":0.26647,"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 (0.33%).
