Name of the Vulnerable Software and Affected Versions Remarshal versions prior to 0.17.1

Description The issue allows for the expansion of YAML alias nodes unlimitedly, making Remarshal susceptible to a Billion Laughs Attack. This can lead to a denial-of-service (DoS) condition when processing untrusted YAML files.

Recommendations For versions prior to 0.17.1, update to version 0.17.1 or later to resolve the issue. As a temporary workaround, consider avoiding the processing of untrusted YAML files until the update is applied.
