CVE-2025-15222Public exploitNetwork attack vector

Authenticated code execution via Base64 object deserialization

Published Dec 30, 2025 · Updated Dec 30, 2025

Deserialization in Dromara Sa-Token 1.44.0 and earlier allows remote authenticated users to execute code via crafted Base64 object data. SaSerializerTemplateForJdkUseBase64 decodes an attacker-controlled string and passes the resulting bytes to ObjectInputStream.readObject without a class allowlist or ObjectInputFilter. Exploitation requires an application to select this serializer, expose an attacker-influenced serialized value, and load a usable gadget class; consequences include code execution, data access, or service interruption.
