Vulnerability Data

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.

MITRE ATT&CK Enterprise TechniquesAI

T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

Uncaught exception in input validation leads directly to process crash, matching Application or System Exploitation for DoS.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-248

Prevents abrupt termination from uncaught exceptions by requiring a defined, preserved-state failure mode.

addresses: CWE-248

Requires pre-defined safe responses for uncaught exceptions so they do not result in undefined or insecure program termination.

detects

Security testing can detect uncaught exceptions before production deployment.

prevents

Secure development lifecycle includes exception-handling standards that reduce uncaught exceptions.

prevents

Application security requirements typically mandate robust error and exception handling.

prevents

Secure architecture principles call for centralized, comprehensive exception management.

prevents

Secure coding standards directly require catching and handling exceptions to prevent crashes or leaks.
