CVE-2026-48038

MEDIUMPre-NVD 5.35.3
EchelonGraph scoreLOW confidence

This medium-severity CVE scores 5.3 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit probability: 0.0%, top 88% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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

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.
