CVE-2026-8735Public exploitNetwork attack vector

Unauthenticated code execution via Fastjson AutoType

Published May 17, 2026 · Updated May 17, 2026

Unsafe deserialization in Oinone Pamirs 7.0 through 7.2.0 allows remote attackers to execute code through the appConfigQuery interface. PamirsParserConfig enables Fastjson AutoType, and JsonUtils.parseMap instantiates attacker-selected classes from a nested JSON string. The authentication-free GraphQL route permits arbitrary remote callers to trigger setter methods and a JNDI lookup, enabling complete server takeover.
