CVE-2019-13116: Mulesoft Mule Unsafe Deserialization

The vulnerability stems from insecure Java deserialization using Apache Commons Collections, but the provided information lacks specific code references or patch diffs to identify exact vulnerable functions. While the advisory references CWE-502 (Deserialization of Untrusted Data) and Apache Commons Collections' known exploit chain (e.g., InvokerTransformer), Mule's implementation details are not disclosed. Common patterns suggest vulnerable code would involve deserialization entry points (e.g., ObjectInputStream.readObject()) in network-facing components, but without concrete evidence of Mule's specific vulnerable code paths or patched methods, we cannot confidently name specific functions. The patched version (3.8.0) likely added validation or removed Commons Collections dependencies, but the absence of commit details prevents precise function identification.
