osquery is a SQL powered operating system instrumentation, monitoring, and analytics framework. Prior to 5.23.1, an unprivileged attacker can read the contents of an osquery file carve until the carve completes and the temporary files are deleted because in-progress carve directories are not created with private permissions. If the carve targets a directory that the attacker controls, arbitrary file reads are possible, such as sensitive local files. This issue is fixed in version 5.23.1.

MEDIUMPre-NVD 4.44.4
EchelonGraph scoreLOW confidence
This medium-severity CVE scores 4.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
