Overview

CVE-2026-25141 is a critical-severity vulnerability. It was published on January 30, 2026 and has a CVSS 3.1 base score of 9.8 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

Orval generates type-safe JS clients (TypeScript) from any valid OpenAPI v3 or Swagger v2 specification. Versions starting with 7.19.0 and prior to 7.21.0 and 8.2.0 have an incomplete fix for CVE-2026-23947. While the jsStringEscape function properly handles single quotes ('), double quotes (") and so on, it is still possible to achieve code injection using only a limited set of characters that are currently not escaped. The vulnerability lies in the fact that the application can be forced to execute arbitrary JavaScript using characters such as []()!+. By using a technique known as JSFuck, an attacker can bypass the current sanitization logic and run arbitrary code without needing any alphanumeric characters or quotes. Version 7.21.0 and 8.2.0 contain an updated fix.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
