BIT-NEO4J-ENTERPRISE-2026-1497 Incorrect privilege assignment in composite databases

Incorrect resolving of namespaces in composite databases in Neo4j Enterprise edition prior to versions 2026.02 and 5.26.22 can lead to the following scenario: an admin that intends to give a user an access to a remote database constituent "namespace.name" will inadvertently grant access to any...

BIT-NEO4J-ENTERPRISE-2026-1471 Caching of authentication context

Excessive caching of authentication context in Neo4j Enterprise edition versions prior to 2026.1.4 leads to authenticated users inheriting the context of the first user who authenticated after restart. The issue is limited to certain non-default configurations of SSO UserInfo endpoint. We recomme...

BIT-NEO4J-ENTERPRISE-2026-14587 Unathenticated connection can hold Bolt channel open

Neo4j's Bolt modern handshake decoder treats an overlong capability bit mask the same way it treats a truncated bit mask. When an unauthenticated client sends a selected protocol version followed by 32 continuation bytes in the capability mask, the decoder resets the reader index and waits for mo...

BIT-NEO4J-ENTERPRISE-2026-1337 Insufficient escaping of unicode characters in query log

Insufficient escaping of unicode characters in query log in Neo4j Enterprise and Community editions prior to 2026.01 can lead to XSS if the user opens the logs in a tool that treats them as HTML. There is no security impact on Neo4j products, but this advisory is released as a precaution to treat...

BIT-NEO4J-ENTERPRISE-2021-34371

Neo4j through 3.4.18 with the shell server enabled exposes an RMI service that arbitrarily deserializes Java objects, e.g., through setSessionVariable. An attacker can abuse this for remote code execution because there are dependencies with exploitable gadget chains...

In @neo4j/graphql 5.2.0+, when both type-level and field-level @authentication directives coexist on a root custom-resolver field, only the type-level rule is evaluated and the stricter field-level rule (e.g., admin-role JWT claim) is silently discarded, allowing any authenticated non-admin clien...

Cypher Injection

Apache Camel Neo4J component is vulnerable to Cypher Injection. The vulnerability is due to insufficient validation of property names in the CamelNeo4jMatchProperties map, where attacker-controlled property names are concatenated directly into Cypher queries, allowing attackers to inject arbitrar...
