Title

joi: Uncaught RangeError on deeply nested input through recursive `link()` schemas

Summary

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.

GHSA-Q7CG-457F-VX79

Vulnerability from github – Published: 2026-06-11 13:27 – Updated: 2026-06-12 19:28

Summary

joi has an uncaught RangeError on deeply nested input through recursive `link()` schemas

Details

Impact

Denial of service via untrapped exception in services validating user-supplied JSON / object input with recursive link schemas.

The blast radius depends on how the application invokes joi: - Highest impact: validate() called without try/catch in a request handler would cause an unhandled exception, potentially crashing the process. - Lower impact: validateAsync() or validate() inside a try/catch, the validation fails, but the error type is RangeError rather than a structured ValidationError, complicating error handling.

Patches

Upgrade to version >= 18.2.1.

Workarounds

Try/catch the validation to avoid uncaught exceptions.
