CVE-2026-46388 | osquery: Unprivileged users can temporarily read file carve contents

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.

Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
