CVE-2023-28118: Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion')

March 20, 2023 (updated March 24, 2023)

kaml provides YAML support for kotlinx.serialization. Prior to version 0.53.0, applications that use kaml to parse untrusted input containing anchors and aliases may consume excessive memory and crash. Version 0.53.0 and later default to refusing to parse YAML documents containing anchors and aliases. There are no known workarounds.
