CVE-2026-117526
Description
A flaw was found in redux-devtools. A local attacker can exploit this vulnerability by supplying a manipulated action parameter to the evalAction function within the Remotedev Server component. This flaw results in code injection, allowing the attacker to execute arbitrary code within the application environment.
Statement
This vulnerability is rated as having Important severity because successful exploitation enables an attacker to achieve arbitrary code execution, compromising system confidentiality, integrity, and availability. While the blast radius allows full execution rights within the running environment, exploitation is constrained by requiring local system access to interact with the development server. In Red Hat environments, redux-devtools is utilized as developer tooling rather than an exposed production service, substantially limiting exposure on standard deployments.
Understanding the Weakness (CWE)
Access Control
Technical Impact: Bypass Protection Mechanism
In some cases, injectable code controls authentication; this may lead to a remote vulnerability.
Access Control
Technical Impact: Gain Privileges or Assume Identity
Injected code can access resources that the attacker is directly prevented from accessing.
Integrity,Confidentiality,Availability
Technical Impact: Execute Unauthorized Code or Commands
When a product allows a user's input to contain code syntax, it might be possible for an attacker to craft the code in such a way that it will alter the intended control flow of the product. As a result, code injection can often result in the execution of arbitrary code. Code injection attacks can also lead to loss of data integrity in nearly all cases, since the control-plane data injected is always incidental to data recall or writing.
Non-Repudiation
Technical Impact: Hide Activities
Often the actions performed by injected control code are unlogged.
