| Título | antlr ANTLR4 4.13.2 Unsafe Java Deserialization Maven Plugin |
|---|
| Descrição | The ANTLR4 Maven plugin (`antlr4-maven-plugin`) uses `ObjectInputStream.readObject()` without setting an `ObjectInputFilter` to deserialize a grammar dependency status file from the build directory. An attacker with write access to the build directory (via shared CI cache poisoning, compromised dependencies that have filesystem access, or a TOCTOU race condition) can replace the status file with a serialized gadget chain and achieve Remote Code Execution on the build server. Confirmed: the deserializer accepts arbitrary class names, attempting to load attacker-controlled classes. |
