Official Description

OneUptime is an open-source monitoring and observability platform. Prior to 10.0.98, OneUptime uses the Node.js' vm module as an isolation primitive. This API was not designed for that and can be escaped via error objects and infinite recursion. This vulnerability is fixed in 10.0.98.

Risk Analysis

This critical vulnerability in OneUptime, prior to version 10.0.98, allows for a bypass of the Node.js vm module isolation, leading to remote code execution. With a CVSS score of 9.9, this flaw presents an extremely high risk, as it enables attackers to escape the sandbox and achieve full system compromise. The absence of an EPSS score means the current exploitation likelihood is not publicly assessed, but the high severity demands immediate attention.

No public exploit is currently known for this vulnerability. Exploitation requires low privileges, but the impact is severe, allowing for remote code execution.

Recommended Action

Upgrade OneUptime to version 10.0.98 or later to fix this vulnerability. Ensure that any isolation primitives used are designed for security and regularly review their effectiveness.

Technical Analysis

CVE-2026-45102 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.9.

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.
