Denial of service via recursive Map serialization
Published Jun 14, 2023 · Updated Aug 2, 2024
Denial of service in FasterXML jackson-databind through 2.15.2 allows attackers to trigger a stack overflow by serializing a cyclic Map. MapSerializer recursively serializes a Map containing itself as a value without detecting the reference cycle, exhausting the Java call stack. The upstream maintainer disputes the vulnerability because external input cannot construct that in-memory cycle and invoke serialization; the demonstrated result is a StackOverflowError.
