To identify risks, you need to check whether you use readObject(), whether there are vulnerabilities in the dependency library, and whether the log configuration contains serialized content. Fix suggestions include: 1. Avoid deserialization of untrusted data; 2. Use JSON/XML to replace native serialization; 3. The input source is controllable and signature/encryption is added; 4. Enable the whitelisting mechanism to limit class loading; 5. Upgrade the dependency library to a secure version; 6. Close en
