AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability involves incorrect resolving of namespaces in composite databases in Neo4j Enterprise edition prior to versions 2026.02 and 5.26.22. Specifically, when an administrator tries to grant a user access to a remote database constituent named "namespace.name", the system may mistakenly grant access to any local database or remote alias simply called "name". Furthermore, if such a database or alias does not exist at the time the command is run, the privileges will still apply if it is created later.
How can this vulnerability impact me? :
The impact of this vulnerability is that users may receive unintended access privileges to local databases or remote aliases that they should not have access to. This could lead to unauthorized access to data or resources within the Neo4j Enterprise environment, potentially exposing sensitive information or allowing actions beyond the intended scope of access.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
