## Affected

- neo4j Enterprise Edition: fixed in 2025.11.2; fixed in 5.26.17

## Description

Neo4j Enterprise edition versions prior to 2025.11.2 and 5.26.17 are vulnerable to a potential information disclosure by an attacker who has some legitimate access to the database. The vulnerability allows attacker without read access to a property to infer information about its value by trying to enumerate all possible values through observing error messages of SET property. We recommend upgrading to 2025.11.2 or 5.26.17 and above, where the issues is fixed.

## What to do
