An authenticated low-privilege user can read or insert TimeSeries samples despite explicit deny rules by exploiting the missing type-name-based access check that causes permission lookups to fail open.","cvssScore":8.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","cwes":["CWE-863"],"vendors":[],"products":[],"references":[{"url":"https://github.com/ArcadeData/arcadedb/security/advisories/GHSA-wjhv-79gv-2pqg","tags":[]},{"url":"https://www.vulncheck.com/advisories/arcadedb-before-26.9.1-timeseries-acl-bypass-via-type-permission","tags":[]},{"url":"https://github.com/ArcadeData/arcadedb/security/advisories/GHSA-wjhv-79gv-2pqg","tags":[]}],"exploitRefs":[{"url":"https://github.com/ArcadeData/arcadedb/security/advisories/GHSA-wjhv-79gv-2pqg","tags":[]},{"url":"https://github.com/ArcadeData/arcadedb/security/advisories/GHSA-wjhv-79gv-2pqg","tags":[]}],"hasPoc":true,"ai":null}
