Denial of Service via Deeply Nested Objects

High
lxsmnsyc published GHSA-3j22-8qj3-26mx Jan 21, 2026

Package

npm seroval (npm)

Affected versions

<=1.4.0

Patched versions

>=1.4.1

Serialization of objects with extreme depth can exceed the maximum call stack limit.

Mitigation:
Seroval introduces a depthLimit parameter in serialization/deserialization methods. An error will be thrown if the depth limit is reached.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
