CVE-2026-46695
CWE-284Published: June 10, 2026· Updated: Jun 17, 2026
Official Description
Boxlite is a sandbox service that allows users to create lightweight virtual machines (Boxes) and launch OCI containers within them to run untrusted code. Prior to version 0.9.0, Boxlite does not restrict the kernel capabilities available inside the container, malicious code can remount the directory in rw mode, thereby gaining write access to that directory. This allows malicious code to perform arbitrary write operations on directories that should be read-only. This issue has been patched in version 0.9.0.
Risk Analysis
This critical vulnerability in Boxlite, a sandbox service, allows malicious code to bypass container restrictions and gain write access to normally read-only directories. With a CVSS score of 10.0, this flaw poses an extremely high risk, as it permits arbitrary write operations and could lead to significant system compromise. The lack of an EPSS score means the exploitation likelihood is currently unknown, but the severity demands immediate attention.
No public exploit is currently known for this vulnerability. However, its network-exploitable nature (AV:N) and low attack complexity mean that if an exploit were developed, it could be easily leveraged remotely without user interaction.
Upgrade Boxlite to version 0.9.0 or later to address this vulnerability. Ensure that all container environments strictly enforce kernel capabilities to prevent unauthorized remounting of directories.
Technical Analysis
CVE-2026-46695 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), with a CVSS base score of 10.0.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
