Overview

CVE-2026-48038 is a medium-severity vulnerability. It was published on July 14, 2026 and has a CVSS 3.1 base score of 5.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

joi is a schema description language and data validator for JavaScript. Prior to 17.13.4 and 18.2.1, denial of service is possible via an untrapped exception in services validating user-supplied JSON or object input with recursive link() schemas. When validate() is called without try/catch in a request handler, deeply nested input can trigger an unhandled RangeError and potentially crash the process; lower-impact paths using validateAsync() or try/catch produce a RangeError instead of a structured ValidationError. This issue is fixed in versions 17.13.4 and 18.2.1.

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.
