The advisory already links the fastjson 1.2.47...1.2.48 compare range as the fix, but not the exact commit. So I'm adding commit 11b92d9f33119ca2af1a3fe6f474de5c1810e686 ("improved autoType check.") as a reference, since it's in that range. It makes MiscCodec load
java.lang.Classvalues with cache=false and changes the default of TypeUtils.loadClass(String, ClassLoader) to stop caching. That closes the mappings-cache bypass of autoType used by the public 1.2.47 RCE (see the vulhub fastjson/1.2.47-rce reference already in this advisory).
