Doc Text:
A flaw was found in seroval. An attacker could exploit this vulnerability by providing a specially crafted JavaScript (JS) object with extreme depth during the serialization process. This could lead to exceeding the maximum call stack limit, resulting in a Denial of Service (DoS) for the application using the seroval library.

Description OSIDB Bzimport 2026-01-22 03:01:21 UTC 
Seroval facilitates JS value stringification, including complex structures beyond JSON.stringify capabilities. In versions 1.4.0
and below, serialization of objects with extreme depth can exceed the maximum call stack limit. In version 1.4.1, Seroval introduces a `depthLimit` parameter in serialization/deserialization methods. An error will be thrown if the depth limit is reached.
