| 설명 | SSRF + BigDecimal Amplification Remote DoS Chain via fromURL() and WRITE_BIGDECIMAL_AS_PLAIN
The combination of JsonLoader.fromURL() (which performs no URL validation) and the default WRITE_BIGDECIMAL_AS_PLAIN configuration in JacksonUtils.newMapper() creates a remote denial-of-service chain. An attacker-controlled URL can serve a tiny JSON payload (e.g., {"x": 1e2000000000}) that expands to ~2GB in memory when serialized via BigDecimal.toPlainString(), causing OutOfMemoryError. |
