cube: Reliance on Untrusted Inputs in a Security Decision
CVE-2026-25958 is a high-severity reliance on untrusted inputs in a security decision vulnerability in cube from Cube-js, with a CVSS 3.1 base score of 7.7 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. Affected cube versions: >= 0.27.19, < 1.0.14; >= 1.1.0, < 1.4.2; >= 1.5.0, < 1.5.13. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.38% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Cube.js to 1.0.14 or 1.4.2 or 1.5.13, whichever matches your release line, or a later version.
- Read the advisory on github.com for workarounds and exact fixed builds.

Official description
Cube is a semantic layer for building data applications. From 0.27.19 to before 1.5.13, 1.4.2, and 1.0.14, it is possible to make a specially crafted request with a valid API token that leads to privilege escalation. This vulnerability is fixed in 1.5.13, 1.4.2, and 1.0.14.

The underlying weakness: Reliance on Untrusted Inputs in a Security Decision
The product uses a protection mechanism that relies on the existence or values of an input, but the input can be modified by an untrusted actor in a way that bypasses the protection mechanism.
How developers prevent this class of flaw
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. With a stateless protocol such as HTTP, use a framework that maintains the state for you. Examples include ASP.NET View State and the OWASP ESAPI Session Management feature. Be careful of language features that provide state support, since these might be provided as a convenience to the programmer and may not be considering security.
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
- When using PHP, configure the application so that it does not use register_globals. During implementation, develop the application so that it does not rely on this feature, but be wary of implementing a register_globals emulation that is subject to weaknesses such as CWE-95, CWE-621, and similar issues.
