Attackers can lure a logged-in backend user with the users[] permission to a crafted GET link to grant administrator rights, deactivate accounts, or lock out the sole administrator.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-352"],"vendors":[],"products":[],"references":[{"url":"https://github.com/redaxo/core/security/advisories/GHSA-mrrj-4f5x-j958","tags":[]},{"url":"https://www.vulncheck.com/advisories/redaxo-before-5.21.3-csrf-token-bypass-via-users-users-privilege-escalation","tags":[]}],"exploitRefs":[{"url":"https://github.com/redaxo/core/security/advisories/GHSA-mrrj-4f5x-j958","tags":[]}],"hasPoc":true,"ai":null}
