GHSA-4j3g-rwwq-4p54
GHSA-4j3g-rwwq-4p54 is a CWE-532 vulnerability in org.neo4j:neo4j. O3 Security confirms whether GHSA-4j3g-rwwq-4p54 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Neo4j Enterprise and Community vulnerable to a potential information disclosure
Blast Radius
org.neo4j:neo4j☕org.neo4j:neo4jReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Neo4j Enterprise and Community editions versions prior to 2026.01.3 and 5.26.21 are vulnerable to a potential information disclosure by a user who has ability to access the local log files.
The "obfuscate_literals" option in the query logs does not redact error information, exposing unredacted data in the query log when a customer writes a query that fails. It can allow a user with legitimate access to the local log files to obtain information they are not authorised to see. If this user is also in a position to run queries and trigger errors, this vulnerability can potentially help them to infer information they are not authorised to see through their intended database access.
Neo4j recommends upgrading to versions 2026.01.3 (or 5.26.21) where the issue is fixed, and reviewing query log files permissions to ensure restricted access. If a project's configuration had db.logs.query.obfuscate_literals enabled, and users wish for the obfuscation to cover the error messages as well, theyneed to enable the new configuration setting db.logs.query.obfuscate_errors once they have upgraded Neo4j.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.neo4j:neo4j. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update org.neo4j:neo4j to 5.26.21 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4j3g-rwwq-4p54 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-4j3g-rwwq-4p54 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-4j3g-rwwq-4p54. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-4j3g-rwwq-4p54 in your dependencies?
O3 detects GHSA-4j3g-rwwq-4p54 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
